• What is the cause and solution for SAP error message WZ219 - Invalid import parameter ?

  SAP Error Message:
  
  WZ219 - Invalid import parameter
  
  Cause:
  The error message WZ219 typically occurs when a function module or a BAPI is called with an incorrect or invalid import parameter. This means that one or more of the input parameters passed to the function module do not meet the expected criteria, such as:
  
  Wrong data type or format
  Missing mandatory fields
  Values outside the allowed range or domain
  Incorrect structure or table contents
  
  In many cases, this error is raised by the function module itself as a validation check to prevent processing invalid data.
  
  Common Scenarios:
  
  Calling a BAPI or function module with incomplete or incorrect data.
  Custom code or user-exits passing wrong parameters.
  Integration scenarios where external systems send invalid data.
  Incorrect parameter mapping in workflows or IDocs.
  
  
  Solution:
  
  
  Check the Parameters Passed:
  
  Review the code or process that calls the function module or BAPI.
  Verify that all mandatory import parameters are filled.
  Ensure the data types and formats match the expected definitions.
  Validate the values against domain or range restrictions.
  
  
  
  Debug the Function Module:
  
  Set a breakpoint at the start of the function module.
  Execute the transaction or process causing the error.
  Inspect the import parameters to identify which one is invalid.
  
  
  
  Consult SAP Documentation:
  
  Look up the function module or BAPI documentation to understand parameter requirements.
  Check SAP Notes for any known issues related to the function module.
  
  
  
  Correct the Calling Program or Interface:
  
  Fix the code or interface sending the parameters.
  Add validation checks before calling the function module to prevent invalid data.
  
  
  
  Test After Correction:
  
  After fixing the parameters, test the process thoroughly to ensure the error no longer occurs.
  
  
  
  
  Related Information:
