Batch management for POSDM interface to ECC

Hi experts,

My client is going to use batch management function in SAP.

Regarding store sales, the POS is going to record the batch number of the articles every time they sell one. This record is to be interfaced back to ECC via POSDM to post GI for the articles of specific batch number.

However, what I discovered is that the message type WPUUMS / WPUBON in ECC do not contain the batch number field.

Could you advise if I have overlooked anything and if you have more experience / knowledge to share?

Thanks so much in advance.
