• What is the cause and solution for SAP error message CKMLAGGR004 - Execute selection before starting aggregation ?

  The SAP error message CKMLAGGR004 ("Execute selection before starting aggregation") typically occurs in the context of the Material Ledger (ML) when you are trying to perform an aggregation process without having executed a selection first. This error is often encountered during the execution of the Material Ledger closing activities, particularly when dealing with actual costing and inventory valuation.
  Cause:
  The error is caused by the following reasons:
  
  Missing Selection: The aggregation process requires a selection of materials or periods to be defined before it can proceed. If this selection is not made, the system cannot determine which data to aggregate.
  Incorrect Sequence of Operations: The aggregation process must follow a specific sequence of operations. If the selection step is skipped or not executed properly, the aggregation cannot be initiated.
  
  Solution:
  To resolve the CKMLAGGR004 error, follow these steps:
  
  
  Execute Selection:
  
  Go to the transaction code related to the Material Ledger (e.g., CKMLCP for closing activities).
  Ensure that you have made the necessary selections for the materials and periods you want to aggregate. This usually involves specifying the company code, plant, material, and the relevant period.
  
  
  
  Check Selection Criteria:
  
  Verify that the selection criteria you have set are correct and that they correspond to the data you want to aggregate. Ensure that there are materials available for the selected criteria.
  
  
  
  Follow the Correct Process:
  
  Make sure you are following the correct sequence of steps as outlined in the SAP documentation for the Material Ledger closing process. This typically includes executing the selection, followed by the aggregation.
  
  
  
  Review Logs and Messages:
  
  Check the logs and any additional messages that may provide more context about the error. This can help identify if there are any other underlying issues.
