[FR] Split Received StockItems into "Packs of n pieces" (in Purchase Orders)

• [X] I checked and didn't find a similar feature request

Problem statement

Often I receive a quantity of an article as stock from a Purchase Order that come in individually packaged boxes or bags - like for example

• 10 power supplies in individual boxes (ordered were: 10x of the part)
• 6 canisters of liquid of 5L each (ordered were: 30L of the part)

These will go onto the warehouse shelf as individual StockItems (like one single power supply, on canister of 5L, etc) and get QR-code labeled as such, each.

For this I currently need to either

• receive the items one by one in the purchase order

or

• receive the items as one StockItem and Transfer sub-quantities out from that - one by one - to split the StockItem accordingly.

Both is pretty slow and repetitive, obviously.

Suggested solution

If we had a "split"-operation in the Received Items StockItem Table where one could enter the pack quantity that the items shall be devided into, that would be super useful.

I guess this would also benefit to other users than me as well..?

Describe alternatives you've considered

Thought about a plugin solution for this, but I would need to recreate a lot of UI (rendering another StockItem table in a custom plugin panel for example) to do that...

Do you want to develop this?

This has been requested before, still have not arrived at a "good" solution

• https://github.com/inventree/InvenTree/issues/

One option may be to create a "supplier bundle" (which contains the listed parts, much like an asembly has a bill of materials), receive that, and then provide an option to "break out" the sub-items?

[simonkuehling]

I think these are different features - the issue your are mentioning seem to have settled to „disassembly“ of assemblies/bundles that can consist of different parts.

My request would be basically the opposite of the „merge“ function, to split/divide a bigger StockItem into several smaller StockItems (of quantity n).

Implementation wise it could be just a repetitive „transfer“ operation until the quantity of the source StockItem is lower or equal to n.

This issue seems stale. Please react to show this is still important.

Not stale

Coming back to this to review against the platform UI, I'd like to propose a pretty simple implementation for this:

What if we extend the /stock/transfer/ API endpoint, adding a new parameter like split_into for the max number of parts per stock item.

I think it could fit very well into the API side, just adding one additional argument to StockItem.move() to drive a looped execution of self.splitStock(). https://github.com/inventree/InvenTree/blob/fb9c117e374443500000845d271d8deabc5ee47f/src/backend/InvenTree/stock/models.py#L2032

On the UI side that could be just an additional column in the "transfer stock" modal table - or it could be its own new action as "split stock", which would be more explicit to a new user I guess.

@simonkuehling are you suggesting that in the "transfer" function, if you are moving a quantity of 100x units, you can specify "split into" quantity (e.g. 5) which would create 20 new stock items each of quantity 5?
