• What is the cause and solution for SAP error message DBMAN462 - NCUM pushdown for &1: key figure &2 has unsupported aggregation 'FIRST' ?

  The SAP error message DBMAN462 indicates that there is an issue with the aggregation method used for a key figure in a query or report. Specifically, the error states that the key figure has an unsupported aggregation type, which in this case is 'FIRST'. This typically occurs when you are trying to push down a query to the database, and the database does not support the specified aggregation method.
  Cause:
  
  Unsupported Aggregation: The aggregation method 'FIRST' is not supported by the underlying database for the specific key figure. Different databases have different capabilities when it comes to aggregating data.
  Query Design: The query or report may have been designed with an aggregation that is not compatible with the database's capabilities.
  Data Source Limitations: The data source being queried may not support certain types of aggregations, leading to this error when attempting to execute the query.
  
  Solution:
  
  
  Change Aggregation Method: Modify the aggregation method for the key figure in the query. Instead of using 'FIRST', consider using a different aggregation method that is supported by the database, such as 'SUM', 'AVG', 'MAX', or 'MIN'.
  
  To do this, go to the query designer in SAP BW or the relevant tool you are using, locate the key figure, and change its aggregation type.
  
  
  
  Check Database Compatibility: Review the documentation for the database you are using to understand which aggregation methods are supported. This can help you choose an appropriate aggregation method for your key figures.
  
  
  Test the Query: After making changes to the aggregation method, test the query to ensure that it runs without errors and returns the expected results.
  
  
  Consult SAP Notes: Check for any relevant SAP Notes or documentation that may provide additional guidance or updates regarding this error message.
