• What is the cause and solution for SAP error message GR665 - The key figure set is the selection set (only one entry is possible) ?

  The SAP error message GR665 indicates that there is an issue with the key figure set in your report or query. Specifically, it means that the system expects only one entry in the selection set for the key figure, but it has detected multiple entries. This can occur in various contexts, such as when working with SAP BW (Business Warehouse) or SAP Analytics.
  Cause:
  
  Multiple Entries in Selection Set: The primary cause of this error is that the selection set for the key figure contains more than one entry, which is not allowed in the context of the operation you are trying to perform.
  Incorrect Query Design: The query or report may have been designed in a way that allows for multiple selections when only a single selection is expected.
  Data Model Issues: There may be issues with the underlying data model or the way key figures are defined in the InfoProvider.
  
  Solution:
  
  Check Selection Set: Review the selection set for the key figure in your query or report. Ensure that only one entry is selected. If multiple entries are selected, modify the selection to include only one.
  Modify Query Design: If you are designing a query, ensure that the key figure is set up to allow only a single selection. You may need to adjust the properties of the key figure in the query designer.
  Use Filters: If you need to analyze multiple entries, consider using filters or other methods to segment the data rather than trying to select multiple entries in the key figure set.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on the key figure settings and how to configure them correctly.
  Test with Different Data: If possible, test the query with different data sets to see if the issue persists, which can help identify if the problem is data-specific.
