• What is the cause and solution for SAP error message RS_HCPR_MODEL103 - Aggregation '&2' of key figure &1 is not possible ?

  The SAP error message RS_HCPR_MODEL103 indicates that there is an issue with the aggregation of a key figure in a data model, typically in the context of SAP BW (Business Warehouse) or SAP HANA. The message states that the specified aggregation for the key figure is not possible, which can occur due to various reasons.
  Causes:
  
  
  Incompatible Aggregation Type: The aggregation type defined for the key figure may not be compatible with the data type or the nature of the data being aggregated. For example, trying to sum up a key figure that is not numeric.
  
  
  Missing Data: If the data required for the aggregation is missing or not loaded properly, the aggregation cannot be performed.
  
  
  Incorrect Configuration: The configuration settings for the InfoObject or the aggregation level may be incorrect, leading to issues in how the data is aggregated.
  
  
  Data Model Issues: There may be issues with the underlying data model, such as incorrect relationships between dimensions or fact tables.
  
  
  Aggregation Level: The aggregation level may not be defined correctly, or the key figure may not be included in the aggregation level.
  
  
  Solutions:
  
  
  Check Aggregation Type: Review the aggregation type defined for the key figure in the data model. Ensure that it is appropriate for the data type of the key figure.
  
  
  Data Validation: Validate the data in the InfoProvider to ensure that all necessary data is present and correctly loaded. Check for any missing or erroneous records.
  
  
  Review Configuration: Go through the configuration settings for the InfoObject and the aggregation level. Ensure that they are set up correctly and that the key figure is included in the aggregation level.
  
  
  Data Model Review: Examine the data model for any inconsistencies or issues with relationships between dimensions and fact tables. Make sure that the data model is correctly designed to support the required aggregations.
  
  
  Rebuild Aggregation: If necessary, try to rebuild the aggregation or refresh the data model to see if that resolves the issue.
  
  
  Consult Documentation: Refer to SAP documentation or notes related to the specific error message for additional guidance and troubleshooting steps.
