• What is the cause and solution for SAP error message /SCMB/PSTRU_MIGR021 - Aggregate &1 is active with DSO &2 storing its data ?

  The SAP error message /SCMB/PSTRU_MIGR021 indicates that there is an issue with the migration of aggregates in the Supply Chain Management (SCM) module. Specifically, it suggests that an aggregate (denoted as &1) is currently active and is associated with a DataStore Object (DSO) (denoted as &2) that is storing its data. This situation typically arises during the process of migrating or restructuring aggregates in the system.
  Cause:
  
  Active Aggregate: The aggregate mentioned in the error message is still active and in use, which means it cannot be modified or deleted until it is deactivated.
  Data Dependency: The DSO is storing data that is linked to the active aggregate, preventing any changes to the aggregate structure or data.
  Migration Process: The error often occurs during a migration process where aggregates are being restructured or moved to a new format or storage.
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Deactivate the Aggregate:
  
  Go to the SAP SCM system and navigate to the area where aggregates are managed.
  Find the aggregate &1 that is causing the issue.
  Deactivate the aggregate. This may involve using transaction codes like /SCMB/AGGR or similar, depending on your system configuration.
  
  
  
  Check DSO Status:
  
  Ensure that the DSO &2 is not in use or locked by any processes.
  If necessary, check for any ongoing data loads or processes that might be using the DSO.
  
  
  
  Perform Migration Again:
  
  Once the aggregate is deactivated and the DSO is free, you can attempt the migration process again.
  Monitor the process for any further errors.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or notes related to aggregate management and migration in SCM for any specific instructions or considerations.
