• What is the cause and solution for SAP error message DBMAN871 - Aggregation &1 for &2 not poss. since other key figure will not be aggr. ?

  The SAP error message DBMAN871 indicates that there is an issue with the aggregation of key figures in a query or report. Specifically, it means that the aggregation for a certain key figure (denoted as &1) for a particular characteristic (denoted as &2) cannot be performed because other key figures involved in the aggregation do not support aggregation.
  Cause:
  
  Incompatible Key Figures: The key figures involved in the aggregation may have incompatible aggregation types. For example, some key figures may be defined as "non-aggregatable" or may have different aggregation methods (like sum, average, etc.) that cannot be combined.
  Data Model Issues: There may be issues in the underlying data model or InfoProvider that prevent proper aggregation. This could be due to incorrect settings in the InfoObject or the way the data is structured.
  Query Design: The query design may not be set up correctly, leading to conflicts in how key figures are aggregated.
  
  Solution:
  
  Check Key Figure Settings: Review the settings of the key figures involved in the aggregation. Ensure that they are set up to allow aggregation and that their aggregation types are compatible.
  Modify Query Design: If the query is designed in a way that causes conflicts, consider modifying it. This may involve changing the way key figures are included in the query or adjusting the aggregation settings.
  Data Model Review: Examine the underlying data model (e.g., InfoCube, DataStore Object) to ensure that it is correctly configured for the key figures and characteristics being used.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on the key figures and their aggregation settings.
  Testing: After making changes, test the query again to see if the error persists.
