• What is the cause and solution for SAP error message RSRTS_CDS183 - Language parameter &1 used in path filter must be hidden ?

  The SAP error message RSRTS_CDS183 indicates that there is an issue with the language parameter used in a path filter within a Core Data Services (CDS) view or a query. This error typically arises when the language parameter is not set to be hidden, which is a requirement for certain scenarios in SAP BW (Business Warehouse) or SAP HANA.
  Cause:
  The error occurs because the language parameter is exposed in the query or CDS view, and it needs to be hidden to avoid issues with data retrieval or filtering. In SAP BW, language parameters are often used to filter data based on the user's language settings, but they should not be visible to the end-user in certain contexts.
  Solution:
  To resolve the error, you need to ensure that the language parameter is set to be hidden in the relevant query or CDS view. Here are the steps to do this:
  
  
  Access the Query Designer:
  
  Open the SAP Query Designer or the relevant tool where the query or CDS view is defined.
  
  
  
  Locate the Language Parameter:
  
  Find the language parameter that is causing the issue. This is typically a filter or selection option in the query.
  
  
  
  Set the Parameter to Hidden:
  
  Change the properties of the language parameter to make it hidden. This can usually be done by selecting the parameter and modifying its settings in the properties panel.
  Look for an option like "Hide" or "Visible" and set it to "No" or "False".
  
  
  
  Save and Activate:
  
  After making the changes, save the query or CDS view and activate it to ensure that the changes take effect.
  
  
  
  Test the Query:
  
  Run the query again to verify that the error message no longer appears and that the query functions as expected.
