• What is the cause and solution for SAP error message RSR_EXPLAIN029 - No exc. aggr. in HANA/BWA for formula variable: non-cumulative context ?

  The SAP error message RSR_EXPLAIN029 indicates that there is no executable aggregation in HANA or BWA for a formula variable that is defined in a non-cumulative context. This error typically arises in the context of SAP BW (Business Warehouse) when working with queries that involve complex calculations or aggregations.
  Cause:
  
  
  Non-Cumulative Context: The error is primarily related to the use of non-cumulative key figures in your query. Non-cumulative key figures are those that do not accumulate over time, such as stock levels or balances. When you try to use these in a context that requires cumulative aggregation, the system cannot process the request.
  
  
  Formula Variables: If you have defined a formula variable that relies on non-cumulative key figures, and the query attempts to aggregate these figures in a way that is not supported, this error will occur.
  
  
  HANA/BWA Limitations: The underlying database (HANA or BWA) may not support the specific aggregation logic required for the non-cumulative context, leading to this error.
  
  
  Solution:
  
  
  Review the Query Design: Check the design of your query and the use of key figures. Ensure that you are not trying to aggregate non-cumulative key figures in a way that is not supported.
  
  
  Adjust Formula Variables: If you are using formula variables, consider modifying them to ensure they are compatible with the context of the query. You may need to change the logic or the key figures used in the formula.
  
  
  Use Cumulative Key Figures: If possible, switch to using cumulative key figures for the calculations that require aggregation. This may involve redesigning your data model or the way you are capturing data.
  
  
  Check Aggregation Settings: Review the aggregation settings in your InfoObjects and ensure they are set correctly for the type of key figures you are using.
  
  
  Consult Documentation: Refer to SAP documentation or notes related to your specific version of BW and HANA/BWA for any additional guidance or known issues.
  
  
  Testing: After making changes, test the query to ensure that the error is resolved and that the results are as expected.
  
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional context on handling non-cumulative key figures.
  SAP Community: Engage with the SAP Community forums to see if other users have encountered similar issues and what solutions they have found.
  BW Modeling: Familiarize yourself with best practices in BW modeling, especially regarding the use of cumulative vs. non-cumulative key figures.
  
  By addressing the underlying causes and adjusting your query design accordingly, you should be able to resolve the RSR_EXPLAIN029 error.
