• What is the cause and solution for SAP error message GR602 - All logical columns have been suppressed ?

  The SAP error message GR602, which states "All logical columns have been suppressed," typically occurs in the context of SAP BW (Business Warehouse) or SAP HANA when working with queries or reports. This error indicates that the query or report is unable to display any data because all logical columns have been suppressed, meaning that the system has determined that there are no valid data points to show based on the current selection criteria or settings.
  Causes:
  
  Data Selection Criteria: The filters or selection criteria applied to the query may be too restrictive, resulting in no data being returned.
  Data Model Issues: There may be issues with the underlying data model, such as missing or incorrect data in the InfoProvider.
  Authorization Issues: The user may not have the necessary authorizations to view certain data, leading to suppression of all logical columns.
  Query Design: The query may be poorly designed, with logical columns that do not have any associated data in the context of the current query execution.
  Aggregation Issues: If the query is set to aggregate data and there are no records to aggregate, it may lead to suppression.
  
  Solutions:
  
  Review Selection Criteria: Check the filters and selection criteria applied to the query. Try relaxing the filters to see if data is returned.
  Check Data Availability: Verify that there is data available in the underlying InfoProvider for the selected time period and dimensions.
  Authorization Check: Ensure that the user has the necessary authorizations to access the data. This can be done by checking the user roles and authorizations in the SAP system.
  Query Design Review: Review the query design in the Query Designer. Ensure that the logical columns are correctly defined and that they are linked to the appropriate data sources.
  Test with Different Users: If possible, test the query with different user accounts to determine if the issue is related to user-specific authorizations.
  Check Aggregation Settings: If the query uses aggregation, check the aggregation settings to ensure they are appropriate for the data being queried.
