• What is the cause and solution for SAP error message /SCWM/LT153 - Changing mixed storage from '&1' to '&2' not allowed in bulk storage ?

  The SAP error message /SCWM/LT153 Changing mixed storage from '&1' to '&2' not allowed in bulk storage typically occurs in the context of SAP Extended Warehouse Management (EWM) when there is an attempt to change the mixed storage type of a storage bin that is designated for bulk storage. 
  Cause:
  
  Mixed Storage Configuration: The error indicates that there is an attempt to change the mixed storage status of a storage bin from one type to another (e.g., from mixed storage to single storage or vice versa) in a bulk storage area. In SAP EWM, certain storage types, especially bulk storage, have restrictions on how mixed storage can be configured.
  System Settings: The system settings for the storage type may not allow changes to mixed storage configurations once they are set, particularly for bulk storage types.
  Data Integrity: The system is designed to maintain data integrity and prevent configurations that could lead to inconsistencies in inventory management.
  
  Solution:
  
  Review Storage Type Settings: Check the configuration of the storage type in the EWM settings. Ensure that the settings for mixed storage are appropriate for the intended use of the storage type.
  Avoid Changing Mixed Storage: If the storage type is set to bulk storage, avoid attempting to change the mixed storage status. Instead, consider using a different storage type that allows for the desired mixed storage configuration.
  Consult Documentation: Refer to the SAP EWM documentation for guidelines on mixed storage and bulk storage configurations. This can provide insights into the limitations and best practices.
  Contact SAP Support: If the issue persists and you believe it should be allowed based on your business processes, consider reaching out to SAP support for further assistance. They may provide insights or solutions specific to your system configuration.
