I'm trying to configure a material determination that associates material A with material B such that when material A is added to a sales order, the same quantity of material B should be added to the order as a sub-item of the material A item.
It seems to work when I add material A with a "stock" item category. However, when I add material A with a "non-stock, order from vendor" item category, it doesn't add the sub-item of material B. Instead, it displays the message "Quantity of 1 EA remains after product selection (item 000010)".
I've gone into SPRO > Sales and Distribution > Sales > Sales Documents > Sales Document Item > Assign Item Categories and made sure that there are records for usages PSEL, PSHP, PSA1, and PSA2 for each of the "non-stock, order from vendor" item categories.
Now that I'm reading more about material determination, I'm thinking that either 1) I'm misunderstanding about the sub-items that are determined, or 2) it's just not designed to work with non-stock materials.
Is a sub-item a material that would be included along with the main item, or is it just intended to show what's being substituted for the main item?
The whole purpose of trying to set this up is for selling remanufactured parts and handling the associated cores that the customer would return. We'd like to automatically add the associated core material to an order when we add a remanufactured part. However, all of the remanufactured parts have to be ordered from the vendor: we don't keep them in stock.
I've started looking at the possibility of using a BOM (Bill Of Material) for the reman / core combination, but it looks like BOM's are used for production orders, and we wouldn't be producing these, just purchasing them.
It seems like it would be similar to free item determination, but the core materials wouldn't be free: there's a cost and price associated with them.
Would greatly appreciate any suggestions and / or insights. Thank you!
