• What is the cause and solution for SAP error message VW801 - Specification SELECTION_SET and SELECT_OPTIONS are alternatives ?

  The SAP error message VW801 indicates that there is a conflict between the use of SELECTION_SET and SELECT_OPTIONS in your report or program. This error typically arises when both options are used in a way that is not allowed by the SAP system.
  Cause:
  
  Conflicting Usage: The error occurs because SELECTION_SET and SELECT_OPTIONS are two different methods for defining selection criteria in an SAP report. They cannot be used simultaneously in the same context.
  Incorrect Program Logic: The program may have been designed to use one method but inadvertently includes the other, leading to this conflict.
  
  Solution:
  
  
  Review the Code: Check the ABAP code where the selection criteria are defined. Ensure that you are using either SELECTION_SET or SELECT_OPTIONS, but not both.
  
  
  Remove the Conflict:
  
  If you are using SELECTION_SET, ensure that you remove any references to SELECT_OPTIONS.
  Conversely, if you are using SELECT_OPTIONS, ensure that SELECTION_SET is not being used.
  
  
  
  Refactor the Logic: If your report requires complex selection criteria, consider refactoring the logic to use one method consistently. 
  
  
  Testing: After making the necessary changes, test the report to ensure that it runs without errors and that the selection criteria work as expected.
  
  
  Related Information:
  
  SELECTION_SET: This is typically used for defining a set of selection criteria that can be reused across different reports or programs.
  SELECT_OPTIONS: This is a more flexible way to define selection criteria directly in the report, allowing for dynamic user input.
  
  Example:
  Here’s a simple example of how you might define selection criteria using SELECT_OPTIONS:
  SELECT-OPTIONS: s_matnr FOR mara-matnr.
  If you were to use SELECTION_SET, it might look like this:
  DATA: sel_set TYPE REF TO cl_selection_set.
  CREATE OBJECT sel_set.
  sel_set->add_field( 'MATNR' ).
  In this case, ensure that you choose one method and remove the other to avoid the VW801 error.
  Conclusion:
  By ensuring that you are using either SELECTION_SET or SELECT_OPTIONS exclusively, you can resolve the VW801 error. Always test your changes to confirm that the report behaves as expected after modifications.
