Storage bin determination for stock data migration purposes

[Former Member]

Hi!
I want to migrate the stocks from an in-house legacy system to SAP WM (SAP ECC).

My problem is that the client is using dynamic storage bins (I have previously worked on static bins only).
The MM part is managed in SAP, the "WM" part is managed in the legacy system.

We can have stocks of a specific material in several storage bins in the legacy system.
How can I transfer the stock to a specific storage bin ?

I think I would use the 311 movement type in mass but I don't know how to manage the WM movement.

Thank you in advance for your help!

Hi Victor,

I assume you can create a file from you legay system. And that this file will contain information about material number, maybe batch number, quantity, storage type, storage bin and maybe stock type (unrestricted, blocked, Q stock), i.e. the data required to create a WM quant.

And I believe to have understood that currently the stock is managed in an MM storage location (with the legacy WM interface somehow) and that you want to move it to a (new, different) MM storage location which has SAP WM attached it.

If that is correct you can move your stock from the current storage location to the new storage location using MM movement type 311. That will put the stock into storage type 921. If you use standard customizing settings for 311 you will get a WM transfer request which can be used to move stock from 921 to the final storage bin. In your case it might be better to adjust 311 to NOT create a transfer order and to use LSMW for mass creating WM transfer orders with LT01 for the stocks in your file.

There are variations to this, but eventually it is (1) move on MM storage location level and (2) move from an interface storage type to the final bin.

Hi Andreas,

This answers perfectly my question.
I already have an ABAP program for the 311 movement type in mass. I'll probably use LSMW for the LT01 transaction.

Thank you a lot!

Best regards,
