• What is the cause and solution for SAP error message SD_CDS_PROJECTION012 - Functions are not supported in Projection View Where-Condition ?

  The SAP error message SD_CDS_PROJECTION012 indicates that there is an issue with the use of functions in the WHERE condition of a projection view in Core Data Services (CDS). This error typically arises when you attempt to use functions or expressions that are not supported in the context of a projection view.
  Cause:
  The primary cause of this error is the attempt to use SQL functions or expressions in the WHERE clause of a projection view. Projection views in CDS are designed to provide a simplified view of data and do not support complex logic or functions in their WHERE conditions. This limitation is in place to ensure that the projection view remains efficient and straightforward.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Review the WHERE Condition: Check the WHERE condition in your projection view definition. Ensure that you are not using any unsupported functions or expressions. Only use simple comparisons and conditions.
  
  
  Refactor the Logic: If you need to apply complex logic or functions, consider moving that logic to a different layer, such as:
  
  Calculation Views: If you need to perform calculations or use functions, consider using a calculation view instead of a projection view.
  ABAP Code: If applicable, you can implement the logic in ABAP code after fetching the data from the projection view.
  
  
  
  Use Filter Conditions: If you need to filter data based on certain criteria, try to use simple filter conditions that do not involve functions.
  
  
  Check Documentation: Refer to the official SAP documentation for Core Data Services to understand the limitations and supported features of projection views.
  
  
  Related Information:

  SAP Notes and Community: Check SAP Notes or the SAP Community for any updates or discussions related to this error message, as there may be specific patches or recommendations available.
