Having issues with the Purchasing products flow

[Circlegent]

Hello again.
I did not know how to label this so I chose the blank issue. Please label correctly, thank you.

I am having an issue with the purchasing of inventory needed to manufacture the products. When I try and go to make a purchase order I get met with 'No Lines Selected' however I cannot see where to even add products to the PO that I am trying to make. Please fill me in on the flow as it is currently setup. I can make a better decision after that.

Thank you.

Purchase lines are possible if in the nomenclature of the order line there is a task requiring a purchase

For example :

I have a command line

With BOM

for a task to be considered as a purchase, you must have a service requiring one of the types in yellow

[SMEWebify]

you can add products from production which will supply stock, only from internal orders (always with purchase tasks)

[SMEWebify]

something else, the product must necessarily exist for it to be stored

Don't hesitate to tell me what you produce (a concrete case that I can project (visualize)

We build internal cabinets and fixtures for ambulances. All together we have a list of well over 2000 parts that go into these on a per cabinet basis ( there are 4 actual final pieces that make up the "cabinet") I see no way of separating the products to purchase per provider. I tried a example on your DEMO site and was able to "order" a product that wasn't associated with the supplier that I had chosen. The flow that usually happens is as follows: All parts to cabinet section gets pulled and delivered to bay for assembly, this lowers the stock amount accordingly, stock numbers are reflected back to the Purchasing Manager, PO gets created per supplier for replenishment of stock. When there are multiple suppliers then they are both associated with the product and Purchase Manager makes the decision on who to order from. Please let me know if this is a help. Thank you very much.

I like your software for the ability to break things down into sub assemblies as well as primary parts. Your BOM as you have it also is a feature that is needed. However the inability to break down the products that are purchased ( I.E. screws, wood material for CNC cutting, metal edging, etc ) by supplier is not something that can be allowed as it would allow for order mistakes and lead to late arrival of orders or even orders not arriving at all due to being sent to the wrong supplier. I hope I have given you a clear enough picture of the standard process here. Again thank you.

If I made a picture, would it look like this?

2 things :

Currently, there is no preferred supplier per item.

It's quite easy to add preferred suppliers per product
Could this be a solution, that when I select a supplier, only the articles concerned by the one if are present?

currently, I do not manage 2-level nomenclatures

I have already prepared some work, but there is still a lot to think about in order to have to manage a recursive nomenclature.
How many levels do you manage?

[Circlegent]

That is very accurate. As far as the sub assembly things my main reason for those is to reference back to things needed that are made here as well and then added to the main assembly. Utilizing that would only be to that end and not multi levels of parts. Your idea above is the right idea. Being able to create a PO that only has the ability to pick from the products of that supplier is what is needed. I thought in the beginning that feature was already there by the "Sort Companies' pull down on the page. When I realized that the products didn't change is why I only mentioned it when I did.

Step two, a little more complicated #314

@Circlegent can you test on demo page

It seems that I have a bug after creating the order
But is the principle what you expect?

Hello,
I tested your addition first thing when I got in. I like it. Limits the products like it is meant to do. However when I go to add a Internal Order to the system for a new product ( simulated :) ) I get a 500 error when trying to add Order Line.

This is the page I am on just before the error:
