• What is the cause and solution for SAP error message GU001 - No fields corresponding to the mask were found ?

  The SAP error message GU001 ("No fields corresponding to the mask were found") typically occurs when there is a mismatch between the fields defined in a selection screen (or input mask) and the fields available in the underlying data structure or table. This can happen in various scenarios, such as when executing a report, transaction, or program that relies on specific input parameters.
  Causes:
  
  Field Mismatch: The fields defined in the selection screen do not match the fields in the database table or structure.
  Missing Fields: The fields expected by the program are not present in the data structure or have been removed or renamed.
  Incorrect Program Logic: The program logic may not be correctly referencing the fields, leading to the error.
  Transport Issues: If the program or report was transported from one system to another, there may be inconsistencies in the data dictionary objects.
  Authorization Issues: Sometimes, the user may not have the necessary authorizations to access certain fields, leading to this error.
  
  Solutions:
  
  Check Field Definitions: Verify that the fields defined in the selection screen match the fields in the corresponding data structure or table. This can be done by checking the ABAP code or the data dictionary (SE11).
  Update Program Logic: If the fields have been renamed or removed, update the program logic to reflect the current data structure.
  Transport Consistency: If the issue arose after a transport, ensure that all related objects (like data elements, domains, etc.) were transported correctly.
  Debugging: Use the ABAP debugger to step through the program and identify where the mismatch occurs. This can help pinpoint the exact location of the error.
  Check Authorizations: Ensure that the user has the necessary authorizations to access the fields in question. This can be checked in transaction SU53 or by consulting with your security team.
