• What is the cause and solution for SAP error message WA685 - & &: Parameter & is not optional ?

  Certainly! Here's a detailed explanation for the SAP error message WA685 & &: Parameter & is not optional:
  
  Error Message Overview
  
  Message ID: WA685
  Message Text: Parameter & is not optional
  Message Class: WA6 (usually related to SAP Workflow or related modules)
  
  
  Cause
  This error occurs when a required parameter is missing or not provided in a function module, method, or workflow step where the parameter is mandatory (not optional). The system expects a value for this parameter, but it was either not passed or passed as empty.
  In SAP, parameters can be defined as optional or mandatory. If a parameter is mandatory, it must be supplied with a value when the function or method is called. If it is missing, the system raises this error.
  Typical scenarios include:
  
  Calling a function module or method without passing all required parameters.
  Workflow container elements missing mandatory parameters.
  Custom code or enhancements where parameter handling is incorrect.
  Incorrect or incomplete data passed from the front end or other systems.
  
  
  Solution
  
  
  Identify the Parameter:
  
  The error message will usually show the parameter name in place of the & placeholders.
  Check the exact parameter name that is missing.
  
  
  
  Check the Calling Code or Workflow:
  
  Review the function module or method call to ensure all mandatory parameters are passed.
  In workflows, check the container elements and ensure all required parameters are filled before the step is executed.
  
  
  
  Debugging:
  
  Use the debugger to trace where the function/module/method is called.
  Check the values of parameters being passed.
  Identify where the parameter is missing or empty.
  
  
  
  Correct the Parameter Passing:
  
  Modify the code or workflow to provide the missing parameter.
  If the parameter is optional in some cases, check the logic to handle those cases properly.
  
  
  
  Check Documentation:
  
  Refer to SAP documentation or function module/method interface to understand which parameters are mandatory.
  
  
  
  Testing:
  
  After correction, test the scenario to ensure the error no longer occurs.

  Example
  If the error message is:
  WA685 & &: Parameter USER_ID is not optional
  It means the parameter USER_ID must be provided but was not.
  You should check the call like:
  CALL FUNCTION 'Z_MY_FUNCTION'
    EXPORTING
      USER_ID = lv_user_id
      ...
  Make sure lv_user_id is not initial or missing.
