• What is the cause and solution for SAP error message /SAPAPO/MA040 - Only enter data on an aggregation level. Entries reset ?

  The SAP error message /SAPAPO/MA040 typically occurs in the context of SAP Advanced Planning and Optimization (APO) when users attempt to enter data in a way that is not aligned with the system's expectations regarding aggregation levels. This error indicates that the system expects data to be entered only at a specific aggregation level, and any attempt to enter data at multiple levels or in a conflicting manner will trigger this message.
  Cause:
  
  Multiple Aggregation Levels: The error usually arises when users try to enter data for multiple aggregation levels simultaneously. For example, if you are trying to enter detailed data while also trying to aggregate it, the system will not allow this.
  Incorrect Data Entry: Users may inadvertently enter data in a way that conflicts with the defined aggregation levels in the planning book or data view.
  Planning Book Configuration: The configuration of the planning book may not be set up correctly to handle the data entry as intended.
  
  Solution:
  
  Check Aggregation Levels: Ensure that you are entering data only at the specified aggregation level. Review the planning book settings to confirm the aggregation levels defined.
  Data Entry Consistency: Make sure that you are not mixing data entries across different aggregation levels. Stick to one level at a time.
  Review Planning Book Settings: If you have access, check the configuration of the planning book to ensure it is set up correctly for the type of data entry you are attempting.
  Use the Correct View: If you need to enter data at a different aggregation level, switch to the appropriate view or planning book that corresponds to that level.
  Consult Documentation: Refer to SAP documentation or help resources for guidance on how to properly enter data in the context of your specific planning scenario.
