• What is the cause and solution for SAP error message RS_HCPR_MODEL032 - Temporal join: Non-cumulative key figure &1 (&2) cannot be mapped ?

  The SAP error message RS_HCPR_MODEL032 indicates an issue with a temporal join in a data model where a non-cumulative key figure is being used incorrectly. This error typically arises in the context of SAP BW (Business Warehouse) or SAP HANA when working with data models that involve time-based data.
  Cause:
  The error occurs because:
  
  Non-Cumulative Key Figure: The key figure in question is non-cumulative, meaning it does not accumulate over time (e.g., it could represent a snapshot value rather than a total).
  Temporal Join: The temporal join is trying to map this non-cumulative key figure in a way that is not supported. Temporal joins are typically used for cumulative key figures that can be aggregated over time.
  
  Solution:
  To resolve this error, consider the following steps:
  
  
  Review Key Figure Definition:
  
  Check the definition of the key figure that is causing the error. Ensure that it is appropriate for the type of join you are trying to perform.
  If the key figure is indeed non-cumulative, consider whether it is necessary to use it in a temporal join.
  
  
  
  Change Join Type:
  
  If possible, change the join type to a different type that does not require cumulative key figures. For example, you might use a standard join instead of a temporal join.
  
  
  
  Adjust Data Model:
  
  If the non-cumulative key figure is essential for your analysis, you may need to adjust your data model to accommodate it without using a temporal join.
  Consider creating a new cumulative key figure that can represent the data in a way that is compatible with the temporal join.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or help resources related to temporal joins and key figures to ensure you are following best practices.
  
  
  
  Testing:
  
  After making changes, test the data model to ensure that the error is resolved and that the data is being processed as expected.
  
  
  
  Related Information:
  
  Key Figures in SAP BW: Understanding the difference between cumulative and non-cumulative key figures is crucial. Cumulative key figures can be summed over time, while non-cumulative key figures represent a state at a specific point in time.
  Temporal Joins: These are used to analyze data over time, and they require careful consideration of how key figures are defined and used.
  SAP Notes and Community: Check SAP Notes for any specific patches or updates related to this error. The SAP Community forums can also be a valuable resource for troubleshooting and finding solutions from other users who have encountered similar issues.
  
  By following these steps and understanding the underlying concepts, you should be able to resolve the RS_HCPR_MODEL032 error effectively.
