  SAP Error Message:
  
  WS451 - Change the selection parameters
  
  Cause:
  The error message WS451 typically occurs in SAP when the system detects that the selection parameters entered for a particular transaction or report are either inconsistent, incomplete, or not allowed in the current context. This often happens in scenarios involving workflow or batch job selections where the parameters do not meet the expected criteria or conflict with each other.
  For example, in workflow-related transactions, if you try to execute a report or a selection screen with parameters that are not valid or are contradictory, SAP prompts you to change the selection parameters.
  
  Solution:
  To resolve the WS451 error, follow these steps:
  
  
  Review the Selection Parameters:
  
  Check all the input fields on the selection screen.
  Ensure that mandatory fields are filled.
  Verify that the values entered are within the allowed range or format.
  
  
  
  Adjust Conflicting Parameters:
  
  If certain parameters are mutually exclusive, make sure only the appropriate ones are selected.
  Remove or modify parameters that cause conflicts.
  
  
  
  Use Default or Recommended Values:
  
  If unsure, reset the selection screen to default values and try again.
  Sometimes, the system expects certain default parameters to be present.
  
  
  
  Check Authorization:
  
  Ensure you have the necessary authorizations to execute the transaction with the given parameters.
  
  
  
  Consult Documentation or SAP Notes:
  
  Look for SAP Notes related to the specific transaction or report you are running.
  Sometimes, patches or updates fix parameter validation issues.
  
  
  
  Debug or Trace (if you have developer access):
  
  If the problem persists, debugging the program or checking system logs might reveal which parameter causes the issue.
  
  
  
  
  Related Information:
  
  Transaction Codes: The error WS451 can appear in various transactions, especially those related to workflow (e.g., SWIA, SWI1) or batch job monitoring.
  SAP Notes: Search the SAP Support Portal for notes referencing WS451 for your specific SAP module or transaction.
  User Guides: Review the user manual or help documentation for the transaction to understand valid parameter combinations.
