[SAP EWM ] Serial number profile changes in EWM

Issue :

Although SAP does not recommend it, it may happen that you want to change the serial number profile of an existing material. If stock has ever existed for this material in the warehouse, the serial number profile is stored in table /SCWM/SERH, and it is no longer changeable despite any changes in the material master in ERP or in EWM.

Solution Approach 

  • As first step you have to remove all stock (including planned stock, which means rejection of all not yet goods receipted stock on existing inbound deliveries) for the material from the warehouse.
  • Set the appropriate serial number profile for the material in ERP.
  • Delete the entry from table /SCWM/SERH for the material.
  • Then you can start using the material with the new serial number profile, when the new stock comes for the material the entry in /SCWM/SERH will be automatically recreated with the relevant data.
Deletion of the entry from the table can be done through debug mode or through the implementing the code proposed by SAP through SNOTE 1498521
