  Cause:
  This error typically occurs in SAP when a query, report, or a selection screen expects exactly two columns to be selected or specified, but the user has selected either fewer or more than two columns. The system enforces this restriction because the underlying logic or function requires exactly two columns to perform its operation correctly.

  When defining key figures or characteristics in reports (e.g., in SAP BW or SAP APO).
  When setting up certain types of queries or data extractions where a pair of columns is mandatory.

  Solution:
  
  Check your selection: Review the columns you have selected or specified in the relevant screen or query.
  Select exactly two columns: Adjust your selection so that exactly two columns are chosen.
  Validate the context: Ensure that the two columns you select are appropriate for the operation you intend to perform.
  Consult documentation: If unsure which columns to select, refer to the SAP documentation or the help text associated with the transaction or report.
