  Error Message
  WXP518: Multiple dimension assignment in listing screen &1
  
  Cause
  This warning message occurs in SAP when a listing screen (usually related to SAP Query or SAP List Viewer (ALV) reports) contains multiple assignments of the same dimension. In other words, the system detects that the same dimension (such as a characteristic or field used for grouping or sorting) has been assigned more than once in the layout or configuration of the listing screen.
  This can happen in scenarios like:
  
  When defining a query or report layout, the same characteristic is added multiple times in the rows or columns.
  When customizing or enhancing ALV reports, the same dimension is inadvertently assigned multiple times.
  In SAP Query, if the user or developer assigns the same field multiple times in the output or selection criteria.
  
  
  Impact
  
  The system warns that multiple assignments of the same dimension may cause confusion or incorrect display of data.
  It may lead to redundant columns or rows in the output.
  The report or query might not behave as expected in terms of grouping, sorting, or filtering.
  
  
  Solution
  
  
  Check the Listing Screen Layout:
  
  Review the layout or configuration of the listing screen (e.g., SAP Query layout, ALV report layout).
  Identify where the same dimension (field/characteristic) is assigned more than once.
  
  
  
  Remove Duplicate Assignments:
  
  Remove or deactivate the duplicate dimension assignments.
  Ensure each dimension is assigned only once in the rows, columns, or filters.
  
  
  
  Adjust Query or Report Definition:
  
  In SAP Query, go to the query definition and check the output fields.
  Remove duplicate fields or characteristics.
  In ALV reports, check the field catalog or layout settings.
  
  
  
  Test the Report/Query:
  
  After corrections, run the report or query again.
  Confirm that the warning message no longer appears and the output is as expected.
  
  
  
  
  Additional Information
  
  This message is a warning (WXP), not an error, so it does not stop the execution but indicates a potential issue.
