  The SAP error message EPS040 indicates that certain input parameters are required for a function module but have not been provided. This error typically occurs when a function module is called without the necessary parameters, which are essential for its execution.
  Cause:
  The error message EPS040 is triggered when:
  
  A function module is invoked without providing all the required input parameters.
  The parameters specified in the function module's interface are not being passed correctly.
  There may be a mismatch in the expected data types or structures of the parameters.
  
  Solution:
  To resolve the EPS040 error, you can follow these steps:
  
  
  Check Function Module Documentation:
  
  Go to transaction SE37 (Function Module) and enter the name of the function module mentioned in the error message.
  Review the documentation and the import parameters to identify which parameters are required.
  
  
  
  Verify Parameter Passing:

  If you are using structures, ensure that they are populated correctly before the function call.
  
  
  
  Debugging:
  
  If the issue persists, consider using the debugger to step through the code and observe the values being passed to the function module.
  This can help identify if any parameters are missing or incorrectly set.
  
  
  
  Consult SAP Notes:
  
  Check the SAP Support Portal for any relevant notes or updates related to the specific function module or error message.
