• What is the cause and solution for SAP error message EPROD035 - Optional parameter &1 was not assigned a value during call ?

  The SAP error message EPROD035 indicates that an optional parameter in a function module or method call was not assigned a value. This typically occurs when a program or function is expecting a value for a parameter that is defined as optional, but it has not been provided.
  Cause:
  
  Missing Parameter Value: The most common cause is that the calling program did not provide a value for an optional parameter that is expected by the called function or method.
  Incorrect Function Call: The function module or method may have been called incorrectly, leading to the omission of the parameter.
  Changes in Function Module: If the function module or method was recently modified to include new optional parameters, existing calls may not have been updated to include these parameters.
  
  Solution:
  
  Check Function Module/Method Definition: Review the definition of the function module or method to understand which parameters are optional and what values they expect.
  Update the Calling Code: Ensure that the calling program assigns a value to the optional parameter if it is necessary for the logic of the program. If the parameter is truly optional and not needed, ensure that the function/module can handle the absence of the value gracefully.
  Debugging: Use the debugger to step through the code and check the values being passed to the function/module. This can help identify where the parameter is being omitted.
  Documentation Review: Check the documentation for the function module or method to see if there are any specific requirements or recommendations regarding the optional parameters.
