• What is the cause and solution for SAP error message RSDD829 - Key figure &1 does not have the aggregation 'SUM' ?

  The SAP error message RSDD829 indicates that a key figure in your query does not have the required aggregation type set to 'SUM'. This typically occurs when you are trying to perform an operation that requires summation on a key figure that is not configured to support it.
  Cause:
  
  Aggregation Type: The key figure in question is defined in the InfoObject with an aggregation type that does not support summation. For example, it might be set to 'Average', 'Count', or another type that does not allow for summing.
  Query Design: The query you are trying to execute may be designed to aggregate data in a way that is incompatible with the key figure's settings.
  Data Model: The underlying data model may not support the required aggregation due to how the data is structured or how the key figure is defined.
  
  Solution:
  
  
  Check Key Figure Definition:
  
  Go to the InfoObject maintenance (transaction code RSD1).
  Find the key figure in question and check its properties.
  Ensure that the aggregation type is set to 'SUM'. If it is not, you may need to change it to 'SUM' if that is appropriate for your business logic.
  
  
  
  Adjust Query Design:
  
  Open the query in the Query Designer (transaction code RSRT or BEx Query Designer).
  Check the properties of the key figure in the query.
  Ensure that the aggregation settings in the query match the requirements for the key figure.
  
  
  
  Rebuild or Adjust the Query:
  
  If changing the aggregation type is not feasible due to business requirements, consider redesigning the query to avoid using that key figure in a summation context.
  
  
  
  Test Changes:
  
  After making changes, test the query again to ensure that the error is resolved.
