  The SAP error message /SAPAPO/OM_ERROR154 indicates that there is an issue with a characteristics container in the liveCache system. Specifically, it means that a characteristics container with the specified GUID (Globally Unique Identifier) already exists in the liveCache, which is causing a conflict when trying to create or update a new characteristics container.
  Cause:
  
  
  Duplicate GUID: The error typically arises when there is an attempt to create a new characteristics container with a GUID that already exists in the liveCache. This can happen due to:
