  The SAP error message C$746, which states "Expansion time & is not allowed for source category &," typically occurs in the context of SAP BW (Business Warehouse) or SAP BI (Business Intelligence) when dealing with queries, data sources, or InfoProviders. This error indicates that there is an issue with the time characteristics or the way the data is being expanded in the query.
  Cause:
  
  
  Incorrect Time Characteristics: The error may arise if the query is trying to expand a time characteristic that is not allowed for the specified source category. This can happen if the time dimension is not properly defined or if the query is trying to access a time period that is not valid for the data source.
  
  
  Data Source Configuration: The data source or InfoProvider may not be configured to handle the requested time expansion. This could be due to missing settings or incorrect mappings.
  
  
  Query Design Issues: The design of the query itself may have issues, such as incorrect filters or aggregations that lead to the error when trying to expand the time dimension.
  
  
  Solution:
  
  
  Check Query Design: Review the query design in the Query Designer. Ensure that the time characteristics are correctly defined and that the query is set up to handle the time dimension appropriately.

  Review Time Characteristics: Ensure that the time characteristics used in the query are valid for the data source. This may involve checking the time hierarchy and ensuring that the time periods being queried exist in the data.
  
  
  Test with Different Time Periods: If possible, test the query with different time periods to see if the error persists. This can help identify if the issue is related to specific time values.
  
  
  Consult Documentation: Refer to SAP documentation or notes related to the specific version of SAP BW or BI you are using. There may be known issues or additional configuration steps required.
