• What is the cause and solution for SAP error message FPGENFG001 - Interface type is not Smart Form-compatible ?

  The SAP error message FPGENFG001: Interface type is not Smart Form-compatible typically occurs when there is an issue with the interface type defined for a Smart Form. This error indicates that the interface being used does not match the expected structure for Smart Forms.
  Cause:
  
  Incorrect Interface Type: The interface type defined for the Smart Form is not compatible with the Smart Form's requirements. Smart Forms expect a specific structure for the interface, which may differ from other types of forms (like SAPscript).
  Missing or Incorrect Parameters: The parameters defined in the interface may not match the expected parameters in the Smart Form.
  Using a Function Module Instead of a Smart Form: If you are trying to call a Smart Form using a function module that is not designed for Smart Forms, this error can occur.
  
  Solution:
  
  
  Check the Interface Definition:
  
  Go to the Smart Form in transaction SMARTFORMS.
  Check the interface section and ensure that the parameters are correctly defined.
  Ensure that the interface type is set to the correct type for Smart Forms (usually a structure or table type).
  
  
  
  Review the Function Module:
  
  If you are calling the Smart Form from a function module, ensure that you are using the correct function module generated by the Smart Form.
  The function module name typically follows the format SSF_FUNCTION_NAME, where FUNCTION_NAME is the name of your Smart Form.
  
  
  
  Adjust Parameters:
  
  Ensure that the parameters you are passing to the Smart Form match the expected parameters in the Smart Form interface.
  If you have added or modified parameters in the Smart Form, make sure to update the calling program accordingly.
  
  
  
  Regenerate the Function Module:
  
  If you have made changes to the Smart Form, regenerate the associated function module by using the "Activate" option in the Smart Form editor.
  
  
  
  Check for Compatibility:
  
  Ensure that the Smart Form is being called in a context that supports Smart Forms. If you are using legacy code or scripts, consider updating them to use Smart Forms properly.
