This error typically occurs in the context of SAP Advanced Planning and Optimization (APO) when you are attempting to make changes to a planning object structure that is currently in use.
  Cause:

  Deactivate or Delete Aggregates:
  
  If you find active aggregates, you can either deactivate them or delete them if they are no longer needed.
  To deactivate an aggregate, select the aggregate and choose the option to deactivate it.
  If you decide to delete an aggregate, ensure that it is not being used in any planning processes.
  
  
  
  Check Dependencies:
  
  Before making changes, ensure that there are no dependencies or processes that rely on the aggregates you are modifying.
  
  
  
  Retry the Operation:
