• What is the cause and solution for SAP error message /AIF/CUSTOM_FUNCTION091 - Screen is empty; enter a valid value ?

  The SAP error message /AIF/CUSTOM_FUNCTION091 Screen is empty; enter a valid value typically occurs in the context of the Application Interface Framework (AIF) when a required input field is left empty or is not populated with a valid value. This error can arise in various scenarios, such as during data processing, interface handling, or when executing custom functions.
  Cause:
  
  Empty Input Field: The most common cause is that a required input field in the AIF interface is empty. The system expects a valid value to be entered.
  Validation Rules: There may be validation rules defined in the AIF configuration that require certain fields to be filled out before processing can continue.
  Custom Function Logic: If you are using a custom function, there may be logic within that function that checks for valid input and raises this error if the input is not as expected.
  Configuration Issues: There could be issues with the configuration of the AIF or the specific interface being used, leading to unexpected behavior.
  
  Solution:
  
  Check Input Fields: Review the input fields in the AIF interface and ensure that all required fields are populated with valid values.
  Review Custom Function Logic: If you are using a custom function, check the implementation to ensure that it correctly handles input values and does not inadvertently trigger this error.
  Consult Documentation: Refer to the AIF documentation or any custom documentation related to the specific interface you are working with to understand the expected input values.
  Debugging: If you have access to debugging tools, you can set breakpoints in the custom function or AIF processing logic to identify where the error is being triggered.
  Check Configuration: Review the AIF configuration settings to ensure that all necessary parameters and validation rules are correctly set up.
