How To Fix FL056 - Where-used list not possible for EXCEPTION parameters

SAP Error Message - Details

• Message type: E = Error

• Message class: FL - Function Builder messages

• Message number: 056

• Message text: Where-used list not possible for EXCEPTION parameters

What causes this issue?

Function module exceptions are currently not handled by the class
CL_ABAP_COMPILER.
It is generally unclear to which function module the exception belongs.
It could belong to some function module of the current function group
(possibly also one of another group). The RAISE statement has fully
dynamic semantics, that is, only at runtime will the system decide
through the call hierarchy where an exception belongs. In this way,
static analyses, such as those done by CL_ABAP_COMPILER and the
where-used list, are excluded.

System Response

Action is interrupted.

How to fix this error?

Use the global search in the function group.

Procedure for System Administrators

• What is the cause and solution for SAP error message FL056 - Where-used list not possible for EXCEPTION parameters ?

  The SAP error message FL056, which states "Where-used list not possible for EXCEPTION parameters," typically occurs when you are trying to generate a where-used list for an exception parameter in a function module or method. This error indicates that the system cannot provide a where-used list for parameters that are defined as exceptions.
  Cause:
  
  Exception Parameters: In SAP, exception parameters are used to handle errors or special conditions in function modules or methods. They are not standard parameters that can be used in the same way as input or output parameters.
  Where-Used List Limitation: The where-used list functionality is designed to track the usage of standard parameters (input/output) but does not extend to exception parameters. This is a limitation in the SAP system.
  
  Solution:
  
  Review Function Module/Method: Instead of trying to generate a where-used list for the exception parameters, review the function module or method directly to understand how the exceptions are being used.
  Check Documentation: Look at the documentation for the function module or method to see how exceptions are defined and handled.
  Manual Search: If you need to find where the exceptions are being called or handled, you may need to perform a manual search in the ABAP code for the function module or method name and look for the exception handling logic.
  Use Debugging: If necessary, you can use the ABAP debugger to step through the code and see how exceptions are raised and handled during execution.
  
  Related Information:
  
  Function Module/Method Definition: Check the definition of the function module or method in transaction SE37 (for function modules) or SE80 (for classes and methods).
  Exception Handling: Familiarize yourself with how exception handling works in ABAP, including the use of RAISE statements and CATCH blocks.
  SAP Notes: Look for any relevant SAP Notes that might address this limitation or provide additional context.
  
  In summary, the FL056 error is a limitation of the SAP system regarding where-used lists for exception parameters. The best approach is to manually review the relevant code and documentation to understand how exceptions are utilized.
