• What is the cause and solution for SAP error message RS_B4HPREP115 - NO2 aggregation is not supported for key figure &1 in &2 ?

  The SAP error message RS_B4HPREP115 indicates that there is an issue with the aggregation of a key figure in a data model or report. Specifically, the message states that "NO2 aggregation is not supported for key figure &1 in &2," where &1 represents the key figure and &2 represents the data model or report.
  Cause:
  The error typically arises due to one of the following reasons:
  
  
  Unsupported Aggregation Type: The key figure you are trying to aggregate does not support the NO2 (non-aggregatable) aggregation type. This can happen if the key figure is defined in a way that does not allow for certain types of aggregations.
  
  
  Data Model Configuration: The data model or InfoProvider may not be configured correctly to handle the specific key figure's aggregation.
  
  
  Incompatible Data Types: The data type of the key figure may not be compatible with the aggregation method being used.
  
  
  Custom Logic: If there is custom logic or calculations applied to the key figure, it may not support aggregation in the way you are attempting.
  
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Key Figure Settings: Review the settings of the key figure in the data model. Ensure that it is configured to support the desired aggregation type. You may need to change the aggregation type to one that is supported.
  
  
  Modify Aggregation Logic: If the key figure is defined with custom logic, consider modifying it to ensure it can be aggregated properly. This may involve changing the calculation or the way data is processed.
  
  
  Review Data Model Configuration: Ensure that the data model or InfoProvider is set up correctly to handle the key figure. This may involve checking the underlying data sources and ensuring they are compatible.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific details on the key figure and its aggregation capabilities. This can provide insights into what types of aggregations are supported.
  
  
  Testing: After making changes, test the report or data model to ensure that the error is resolved and that the aggregation works as expected.
  
  
  Seek Support: If the issue persists, consider reaching out to SAP support or consulting with a technical expert who specializes in SAP BW or the specific module you are working with.
  
  
  Related Information:
  
  SAP BW Documentation: Review the official SAP BW documentation for information on key figures, aggregation types, and data modeling best practices.
  SAP Community: Engage with the SAP Community forums to see if others have encountered similar issues and what solutions they have found.
  Transaction Codes: Familiarize yourself with relevant transaction codes (e.g., RSA1 for Data Warehousing Workbench) to help you navigate and troubleshoot the data model.
  
  By following these steps, you should be able to identify the root cause of the error and implement a solution to resolve it.
