• What is the cause and solution for SAP error message RSRTS_CDS158 - SortDirection ignored: already defined for characteristic &1 by field &2 ?

  The SAP error message RSRTS_CDS158 indicates that there is a conflict in the sorting direction for a characteristic in a CDS (Core Data Services) view or a query. Specifically, it means that the sorting direction for a characteristic (denoted as &1) has already been defined by another field (denoted as &2), and therefore, the new sorting direction is being ignored.
  Cause:
  This error typically arises in the following scenarios:
  
  Duplicate Sorting Definitions: When you have multiple fields or characteristics in your query that attempt to define a sorting order for the same characteristic.
  Inconsistent Query Design: The query design may have conflicting sorting settings, where one field is trying to sort in one direction (ascending or descending) while another field is trying to sort in the opposite direction for the same characteristic.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Review Query Design:
  
  Open the query in the Query Designer or the relevant tool where the query is defined.
  Check the characteristics and fields that are included in the query.
  Identify if there are multiple fields trying to sort the same characteristic.
  
  
  
  Consolidate Sorting:
  
  Decide on a single sorting direction for the characteristic in question.
  Remove or adjust the sorting settings for the conflicting fields to ensure that only one field is defining the sort order for that characteristic.
  
  
  
  Test the Query:
  
  After making the necessary adjustments, save the query and execute it again to see if the error persists.
  
  
  
  Check for CDS View Definitions:
  
  If you are working with a CDS view, check the definition of the view to ensure that there are no conflicting sorting definitions within the view itself.
  
  
  
  Consult Documentation:
  
  If you are unsure about the sorting settings or how to adjust them, refer to SAP documentation or help resources related to Query Designer or CDS views.
