• What is the cause and solution for SAP error message RSDD079 - Editing of aggregate &1 in main process ?

  The SAP error message RSDD079, which states "Editing of aggregate &1 in main process," typically occurs in the context of SAP BW (Business Warehouse) when there is an attempt to edit or modify an aggregate that is currently being used in a main process. This can happen during various operations, such as when trying to change the structure of an aggregate or when performing data loading activities.
  Cause:
  
  Active Usage: The aggregate is currently being used in a main process, such as data loading or reporting, which prevents any modifications.
  Locking Mechanism: SAP BW employs a locking mechanism to ensure data integrity. If an aggregate is locked by another process, you will not be able to edit it.
  Incorrect Process Flow: The process you are trying to execute may not be correctly sequenced, leading to attempts to edit an aggregate that is still in use.
  
  Solution:
  
  Check Active Processes: Ensure that no data loading or reporting processes are currently using the aggregate. You can check the process chains and monitor transactions to identify any active processes.
  Wait for Completion: If there are active processes, wait for them to complete before attempting to edit the aggregate again.
  Release Locks: If you suspect that a lock is causing the issue, you can use transaction SM12 to check for and release any locks related to the aggregate.
  Review Process Chains: If you are working with process chains, ensure that the sequence of processes is correct and that the aggregate is not being used in a way that conflicts with your editing attempts.
  Use Transaction RSD1: If you need to make changes to the aggregate, you can use transaction RSD1 to access the InfoObject and check its settings.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as RSD1 (for InfoObjects), RSD2 (for InfoProviders), and SM12 (for lock entries).
  SAP Notes: Check for any relevant SAP Notes that may address specific issues related to aggregates and error RSDD079.
  Documentation: Review SAP BW documentation for best practices on managing aggregates and understanding the locking mechanisms in place.
