Description

hey guys, in 5 minutes we will start traditional MSI weekly demo accessible by this URL - https://magento.zoom.us/j/355586473

Agenda:
1. @roman.kis RSS feed for Low Stock Qty notification
2. @Vjacheslav Moskalyuk will demonstrate bugfix for notifying Qty configuration
3. @aleron75 will share the current status of IsProductSalableInRequestedQty service which we use for both Quote and Checkout
4. @iminiailo will demonstrate Source Deduction as a result of Source Selection Algorithm processing (brought you by @seruymt)

A

I'm starting the recording of the meaning and as usual, let's, let's follow the unknowns agenda, and today today we will show you several stories which we prepare it for the demo, but actually most of the time.

A

During this week we spent on some architectural stuff, and we we spend on interface as we need for for the souls deduction for wood and for checkout later during this meeting, Alessandra will share as a status of this story, and this is pretty important stuff, because it's supposed to tied all the work we've done before the source deduction which will present today and the source selection algorithm. And it's a quote when we play some put some products into the judges, shopping cart.

A

So all this story, speaking Putin, is supposed to and I tie all the pieces of puzzle which we currently have. But let's follow that announced agenda and the first one would be Roman keys, which will show you the story devoted for the RSS feed for the lows, low stock notification.

A

Some romance will feature. Failure screen make a presentation Cairo.

B

Okay, I will show you how RSS feed work on MSI is just a prototype. It need to refactor, but it works for now. So I have a Magento installer to disc /url and I also have ad for Google ROM.

B

Here I manage it. I subscribe it to notify stock RSS feed. Ok enough, I have five products, which is, if I'd, let's find some product, for example, product six.

B

Okay, let's set notify stock here, 7, 9 and 11 and I three. So now, if I save, let's set 1315 so now, if I say product, they should disappear from here, but I need to flush cash because RSS feed is cached and they have their own Wi-Fi. So we will not read we just flash cash. Let's refresh.

B

So really as they disappear, only a simple product eight is present. Let's set, for example, five. Four three, let's set here I use one T default default in g7. In my configuration, so now they all should appear safe, flash cash.

B

B

Yes, they all appeared and, as you can see, I changes a message I added source here is this source name and source code and not need I, don't know what message should be is called mark you'll answer to me how it should be shown.

B

Let's set game here: fifteen and this one's resource free should disappear, can source free? What is this one.

B

Three, yes, it's disappeared, and it's also worked with manage stock disabled. So if I go to get a lock in, ran three and disabled manage stock, say of config flash cash, they should all disappear from here.

B

Product six, maybe oh, yes, use kind of exciting, save.

B

It should disappear.

B

Yes is disappeared but if I turn on mana stock for my broker product press safe for now, I should see to product to search items with default source and source stone. Let's flash cache the first page.

B

And here I see only two stores items, so this works as if global manage stock is enabled. Is we have the same results? So let's I show you again that, for example, here I put eight use the fall, and here I put six and use the fall so use default. We have seven.

B

Flash so again, we should have two products on the follow source and source free.

B

It's the same product, the fall source and source free, so I think that's all from my side. Any questions maybe.

B

Yes, I, don't listen louder so.

A

We asked whether this functionality support the quarters. Oh no.

B

This doesn't support the chorus.

A

Support of the chorus was implemented previously in the current version of magenta.

C

A

B

I will check its own.

D

And I have one more question, so you said that the RSS feed is cached and we need to flush the cache every time we have some change in the source quantity. So what happens if the customer buys the product and it becomes slow stock, so the RSS feed will be natural until the cache it.

B

Is kept but this cache has his his own lifetime, so it will be done automatically. Ok,.

A

The question guys.

A

If no, we can proceed to other other ticket, Thank You Ramon for presentation it was, it looks nice, don't equation. We need to clarify regarding the back orders.

A

So the next one gonna be which Islam will demonstrate, use a box. We recently fix for the mattify quantity configuration.

E

Show my screen we currently on developer branch. We have a back that notify quantity use default, this checkbox doesn't work and after you even save product, the check box will be unsealed and this buck was fix it and notify quantity.

E

This value we set in configuration cut a lock in italica inventory, MSI, currently.

E

But later it will be moved to inventory. So in my configuration, I said value for notification, 5 and I go to the product like I, have simple products and previously I saved the different value for x entity. But when I check this checkbox, you may see maybe already that it's a change in the file and after I save it.

E

We may see that notified quantity changed into fire.

E

That's all. Thank you for attention. Thank.

A

A

So now Alessandra will share with us his update on a really important task for us. He is currently working on.

F

Yes in my screen, hello, everyone I started from this issue that is adding a new service for for checking whether product is scalable in the context of the shopping cart. So I already began working on that and submit to the work in progress to request about this, what I'll show you is utterly not working code, because I'm in the middle of of implementation of this service. Basically, what we do here is introducing a new service called miss product saleable for requested quantity and I'll. Show you the interface, which is, as usual, a single method.

F

Interface will be executes that in this case differently from this, we defined has to return a return value, and this is what I'm implementing right now. So this is product syllables of interface, which will convey both this ability flag and the errors that eventually are.

F

As in the East saleable, we exploit the was composable chain of conditions, so, as you can see here, this product saleable, which is agnostic about the state context, is defined here with these four conditions ordered by this number and these products for requested corn. That is a chain of three conditions.

F

The the new one that I'm implementing is these called is correct. Quantity I'm, still in the middle of development, but basically is correct. Quantity is, is the condition which checks whether the requested quantity is within certain limits so lower and the hospital limits, because you know that we can. We can set minimum and maximum quantity for the shopping cart for product, and it also has to check for, for example, if we have quantity increments enabled that the quantity that put into the car is exactly is an exact amount of quantity and.

F

In the scope of this implementation, we are introducing some specific interfaces, as you can see, and I think that's almost all at the moment. Sorry, if I can't show you some.

F

This is important because the service will be used, as mentioned in the context of of sales. Indeed, these services implemented in the inventory sales module, as shown here. If you have any question, please feel free to ask so.

C

If I'm sent directly, the service will be called during place order, operation right.

F

During place order, but also when adding a product to the shopping, cart to check whether whether that the product can be added to the shopping cart, because this condition have to be checked while are being the product in the shopping. Cart.

F

Not only during checkout.

C

Can you show me, can you please show again the list with the configuration options.

F

So they are defining that the I XML I, hope that you can see both of them yeah.

F

Here the list of his products available checks for backorder, managed the core doctrine enabled manage stock, enable saleability with reservations and min quantity. This is the ones for his product, saleable it's not in the context of solubility of sorry of shopping cart, and this one did three they're less, because the East card quantity already checks for cell ability within reservation. So basically this the last two of the is saleable is product. Syllable service are in condensed into the east, correct quantity here and the first two are the same.

F

So we check for back order, because if the recorder is enabled we don't have to apply restrictions. If we don't manage stock, you don't have to buy restrictions, and otherwise we have to check for cart. Quantity.

C

Okay, do we have one is okay, let's do we have documentation for this.

F

We have the issue at the moment where we describe this. Probably this.

F

Part of our week, I think we caught me making this, because this.

E

F

My storm, so we probably had have to fix it in our week.

C

Okay, thank you. I.

F

A

So yeah we will finish documentation. We already have some of the documentation and we will provide like dedicated article in homicide scope just after you finish, because currently we are still a little bit playing around with this interfaces so document. So we already have the documentation in the issue description and will provide the key presentation, I believe till next demo, when we will integrate this service in both wood and.

C

Accessibility had discussion about blaming is everyone? Okay, with such naming for such names for the sector faces I.

C

F

Open to two changes, no problems.

F

Do you have any some means.

C

I'm just wondering if it was already discussed if everyone is okay with it with such names, we.

A

Created a public vote and and most of people position.

A

Okay, thank you, your update, so let's proceed war.

A

For next option next bullet item: in a you know the game agenda and the last but I hope not the least gonna be me who will demonstrate assault deduction actually that sort deduction was done by by Sergei who's, currently on the poll and I'm just a company to this really genius contributor, but he's a little bit shy and that's why I will make the demonstration by my own, so I will share my screen and.

A

They currently I will show you so what I am going to present when a previous Dima will really show you how we launched the source selection algorithm as it at this time of order shipment.

A

But on a previous demo, we did not make any source detection as the result of this algorithm, and today, I will show you, the cool business flow from order creation to to place in that order, create a reservation for that order and the making a shipment and launching the source selection algorithm and applying that algorithm so appliance that they did deductions or deduction for particular source items. So let let's see what we currently have in our predefined state. So currently we have two stocks.

A

The stock we're probably interested in is Europe stock and in Europe stock. If you'll go deeper, will see that there are three sources assigned to this stock and these sources are Italy Poland in Ukraine, and here we need to mention that this is an order, because you know here we can move this order and actually the order describe the priority between the sources. So currently, the Italy has the highest priority.

A

The Poland has little little less priorities in Italy and the least priority as Ukraine, so actually the order will matter for the source, selection or the reason, because current source selection algorithm. We have Iran and provide the rearrangement of of the source item based on the priority factor. So now, let me show you the products.

A

So currently we interested in two products that simple product test, simple product, to don't pay attention on this little JavaScript issue we'll have it. We already have a dedicated issue to fix the sound, but currently what we are mostly interested in, let's go and see to these particular products and what the stocks we have for this product.

A

A

Country we have the simple product is in stock on all the sources and has a quantity on the Poland's. Are it assigned to the Poland and Ukraine and has quantity 100 per each of these sources? And if you will go to the simple product to.

A

You this product assigned to Italy in a Ukraine and also the number of the amount of the product, is 100 per each of these sources. So, as you can see, we have like eight pairs, Italy in Ukraine and Poland in Ukraine. So let's now place an order. These purposes, let's go to the customer page.

A

So the customer would like to place order for.

A

They're going to be a John Doe and let's place an order for the John.

A

So here we need to choose this product.

A

Let's filter out this simple.

A

And, for example, we would like to order tests simple product in quantity, 10 and test simple product in the quantity 5- and here we add this product to the order items and let's use a shipping method for the order. Let's make some small face. Small present for the drum pod Ronan will make a ship free shipping so unless finally place an order.

A

So now we have the order created and to demonstrate that we can I.

A

Will show you that we placed a reservation.

C

A

So here you see that we place two reservation for each of the product in a in our second second stock ID, which describes the Europe stock with quantity, minus 5 and minus 10. And now, let's proceed to to the shipment step.

A

But actually before that we can see not even procedure to the shipment step. We can see as a store selection and see the idea of the from which sources we are going to fulfill the border. So if you remember we have we have the we have product test, simple product which is assigned to Poland and Ukraine and Italy, and the product test test, simple product which is sent to Italy in Ukraine.

E

A

Taken into account that Ukraine has has lowest priority among all of them. We, our source selection, algorithm aching. The sorting by priority should not make any delivery from Ukraine, so the product test, simple product supposed to be delivered from Poland and the product test simple product supposed to be delivered from Italy.

A

So you see that Ukraine does not take part in the order fulfillment. So let's go now to the shipment step. I.

C

Have question about you act so that so we will have multiple sources and product available and sources is exo-k with such page, because it's if you have a lot of sources you, it is not immediately visible where oh, where could be shipped from. We.

A

Will we already have ue X provided by European bonnet and actually the main idea here so we'll we will add some more functionality on UX, because currently years has just read only but what we are going to add here. We need to provide the possibility of editing the whole source selection, Elbrus I will I will actually show you I suppose. No.

C

No, no, no need to distract just.

A

C

So, as my main main answer to my question is this is not final yet.

A

So at the top of the list we would have the source item from which we are going to deliver Samson and at the bottom we will show the source item from which on which there is product to be delivered, but we are not going to deliver and will provide to merchants inability, for example, to read just on top of the default result of source selection algorithm his own changes not just to rely on a result of source selection.

A

Okay, that was the idea, so we will change the change, the look and feel and we will provide an ability to edit the default for section. So currently we can submit shipment. We are submitting shipment here we see that shipment has been created and now, let's go to the product pages and.

A

Refresh these pages, so we can see that stock has been updated for the test, simple product from which, which we delivered from the Italian source. Now, let's go to yeah to test simple product, 1 refresh the page and see that this product has been delivered from the poland source. Also now we need to verify that we create the compensation reservation. This way, let's return to my high security console and my scale connection and launch this.

A

The same query and you'll see that we create compensation reservation of 4 for these items, so here you see that we created +5, + + 10 reservation. Currently we have.

A

Some small issue that we created reservation 0 reservation for Ukraine and we will fix it out pretty soon. But actually, even you know, the zero reservation for Ukraine don't affect the the final quantity. So you see that currently we are up in the running. We make the source deduction and we in the scope of the source deduction. We also create the computational reservation. This logic happens in the same transaction, so.

A

We support the atomicity and the granularity of this change so.

C

You don't drop reservations, you do you create compensation. Alright, there is have compaction planned for this table. We.

A

I will show you.

A

We we have a cron mechanism and in this Crone mechanism we can we actually we do a cleanup and how that they cannot work clean up, make a grouping, and if it sees that there are reservation items and the total quantity of that items, grouping together will equal to zero. We will just eliminate this iteration ultimately, but.

C

If it's not equal zero, it.

A

Leaves in a reservation so it it doesn't influence the total quantity. So probably if it does not equal zero, it means that we have still open orders which we need to process. We can. We can introduce more sophisticated mechanism and we discarded with a little this Alessandra. So, for example, we can find if we have minus five plus five minus five.

A

We can remove minus 5 and plus five and leave just minus five, but currently it just not so important for us and potentially it could just improve, not even performance, but it could decrease the capacity of the table in future. Well,.

C

I would say it might be, I agree, it might be not the highest priority, but this approach- I, wouldn't say it's very safe. If there is some condition where we have hanging order or head hanging reservation, then for some for something for that product, you will never be able to compact its reservation. So I would request something like do.

A

C

Compaction based on order based on a per border like so, if you, if you see that there is a per.

D

Order there is.

C

E

C

Out clean them up not just not calculate total quality.

C

A

It was our main idea not to make coupling between reservation and orders, for example, because.

C

Don't think it's a it's a coupling in from this perspective order, ID I think you have order ID in that table right.

E

C

Okay, can you show the table again.

A

D

Have just reservation ID.

A

Stock ID s, Q quantity and meter metadata, okay,.

C

We'll discuss it during grooming meeting I would the risk of this solution and, if you add order, ID I, don't think it will be coupling. It will be just in from this perspective, we'll use just as a label that.

A

Only we I am barely sure that will all the reservation would be coupled to the order ID, because other business processes could lead to reservation creation, and it could be not not an order. For example,.

C

Yeah, that's what I'm saying we could do that is needed. Let's discuss in more details on grooming, but if unit it can be used, it can be called even not an order idea like a label or something like that.

A

Actually, that was the reason why we had metadata okay.

C

So, let's discuss it increment. Thank you again.

A

Looks like it was the last option. You know today's agenda. If you have any question, please please you can raise it now or if there is no zero, no question just pinga cinema sites like channel, we are always open. We are always ready for for your question and to provide your support for any Affairs. You have devoted with MSI and.

A

Your participation for your time, it is always important for us to have you on meters.

A

Thank you guys, bye.
