  SAP Error Message:
  
  WX601 - Enter valid parameter
  
  Cause:
  The error message WX601 typically occurs in SAP when a user inputs an invalid or incorrect parameter value in a selection screen, report, or transaction. This means the system expects a certain type or format of parameter, but the entered value does not meet these criteria. It can happen due to:
  
  Entering a parameter value that is outside the allowed range.
  Providing a parameter in an incorrect format (e.g., text instead of numeric).
  Leaving a mandatory parameter blank.
  Using a parameter value that is not recognized or supported by the program or transaction.
  
  
  Solution:
  To resolve the WX601 - Enter valid parameter error, follow these steps:
  
  
  Check the Parameter Value:
  
  Verify the value you entered for the parameter.
  Ensure it matches the expected data type (numeric, date, text, etc.).
  Confirm it is within the allowed range or list of values.
  
  
  
  Refer to Field Help:
  
  Use the F4 help (value help) on the parameter field to select a valid value.
  This helps avoid manual entry errors.
  
  
  
  Mandatory Fields:
  
  Make sure all mandatory parameters are filled.
  Blank mandatory fields can trigger this error.
  
  
  
  Review Documentation:
  
  Check the documentation or help for the transaction or report to understand valid parameter values.
  
  
  
  Check for Custom Validations:
  
  Sometimes, custom ABAP code or user exits validate parameters.
  If you suspect this, consult your ABAP developer or support team.
  
  
  
  Clear and Re-enter:
  
  Clear the parameter field and re-enter the value carefully.
  
  
  
  System or Program Bug:
