• What is the cause and solution for SAP error message WLC_PARALLEL007 - Input parameter &1 of function module &2 must be filled ?

  The SAP error message WLC_PARALLEL007 indicates that an input parameter for a function module is not filled as required. This error typically occurs in the context of parallel processing, where certain parameters must be provided for the function module to execute correctly.
  Cause:
  The error is caused by one of the following reasons:
  
  Missing Input Parameter: The function module being called requires a specific input parameter (denoted as &1 in the error message) that has not been provided or is empty.
  Incorrect Configuration: The configuration or setup of the function module may not be correct, leading to the requirement of parameters that are not being met.
  Data Issues: The data being passed to the function module may not be valid or complete, resulting in missing parameters.
  
  Solution:
  To resolve the error, you can take the following steps:
  
  
  Check Function Module Documentation: Review the documentation for the function module (&2 in the error message) to understand the required input parameters and their expected values.
  
  
  Debugging: Use the SAP debugger to trace the execution of the program and identify where the input parameter is not being filled. Look for the point in the code where the parameters are set before the function module is called.
  
  
  Parameter Initialization: Ensure that all required parameters are initialized and filled with valid data before calling the function module. This may involve checking the logic that populates these parameters.
  
  
  Error Handling: Implement error handling to check if the parameters are filled before the function module is called. This can prevent the error from occurring and allow for graceful handling of missing data.
  
  
  Consult with Developers: If you are not the developer of the program, consult with the development team to understand the expected input and any recent changes that may have affected the parameters.
  
  
  Testing: After making changes, thoroughly test the program to ensure that the error is resolved and that the function module executes as expected.
  
  
  Related Information:
  
  Function Module: A function module in SAP is a reusable piece of code that can be called from various programs. Each function module has a defined interface that specifies the input and output parameters.
  Parallel Processing: This error is often related to parallel processing scenarios where multiple instances of a function module are executed simultaneously. Ensure that the parameters are correctly managed in such scenarios.
  SAP Notes: Check the SAP Support Portal for any relevant SAP Notes that may address this specific error or provide additional guidance.
  
  By following these steps, you should be able to identify the cause of the error and implement a solution to resolve it.
