• What is the cause and solution for SAP error message FDT_EXPRESSIONS522 - Function &1 does not have an exporting or returning parameter ?

  The SAP error message FDT_EXPRESSIONS522 indicates that a function module or method you are trying to call does not have any exporting or returning parameters defined. This can occur in various contexts, particularly when working with function modules in ABAP or when using expressions in the SAP Fiori or SAP UI5 environments.
  Cause:
  
  Function Module Definition: The function module or method you are trying to call is defined without any exporting parameters or returning values. This means that it does not provide any output to the caller.
  Incorrect Call: You may be trying to call a function that is not designed to return any data, but your code expects it to do so.
  Misconfiguration: There might be a misconfiguration in the way the function is being called, such as incorrect syntax or parameters.
  
  Solution:
  
  
  Check Function Module/Method Definition:
  
  Go to transaction SE37 (for function modules) or SE80 (for methods in classes) and check the definition of the function/module you are trying to call.
  Ensure that it has the appropriate exporting or returning parameters defined.
  
  
  
  Modify Your Call:
  
  If the function/module is not supposed to return any data, modify your code to not expect any output from it.
  If you need to retrieve data, consider using a different function/module that provides the required output.
  
  
  
  Review Documentation:
  
  Check the SAP documentation or the function module's documentation to understand its intended use and parameters.
  
  
  
  Debugging:
  
  If you are unsure why the error is occurring, use the debugger to step through your code and see where the function call is made and what parameters are being passed.
  
  
  
  Consult with Colleagues or SAP Support:
  
  If you are still unable to resolve the issue, consider reaching out to colleagues who may have experience with the specific function/module or contact SAP support for assistance.
  
  
  
  Related Information:

  ABAP Development: Understanding how to define and call function modules correctly is crucial for ABAP development.
  Error Handling: Implement proper error handling in your code to manage situations where a function/module may not behave as expected.
  
  By following these steps, you should be able to identify the cause of the error and implement a suitable solution.
