How To Fix TW165 - Function & does not fit into the existing function group (&)

SAP Error Message - Details

• Message type: E = Error

• Message class: TW - R3trans - Messages

• Message number: 165

• Message text: Function & does not fit into the existing function group (&)

What causes this issue?

A function module with LIMU FUNC ... was transported in the transport
request.
An import is only possible if this function module belongs to the same
function group in the target system and
has the same internal number as in the source system.
These conditions were not observed in the target system.
This problem can occur,
if an entry LIMU FUNC ... is included in a transport request manually
in the object list editor,
or if a function module is deleted, and then created again under the
same name in another function group, and deletion and creation are
recorded in the same change request.

System Response

The function module was not imported.

How to fix this error?

You can remove the error by making another transport from the source
system. Transport the affected function groups once more in their
entirety. To do this, use the transport object R3TR FUGR ... .
You can avoid the second type of error (deletion and creation in
another function group) as follows:
In the ABAP Workbench use the function <LS>Reassign</>, or record the
deletion and the new creation in separate change requests.
Release the change request with the deletion before you release the
change request with the new creation.

• What is the cause and solution for SAP error message TW165 - Function & does not fit into the existing function group (&) ?

  The SAP error message TW165 indicates that there is an issue with a function module or function that is being referenced in your ABAP code. Specifically, the error message states that the function does not fit into the existing function group. This typically occurs when there is a mismatch between the function module and the function group it is supposed to belong to.
  Cause:
  
  Function Module Misplacement: The function module is not correctly assigned to the function group. This can happen if the function module was created or modified incorrectly.
  Transport Issues: If the function module was transported from one system to another (e.g., from development to production), it may not have been included in the correct function group.
  Naming Conflicts: There may be naming conflicts or issues with the function group that prevent the function from being recognized properly.
  Inconsistent Development: If multiple developers are working on the same function group, inconsistencies can arise if changes are not properly coordinated.
  
  Solution:
  
  Check Function Group Assignment: Verify that the function module is assigned to the correct function group. You can do this by navigating to the function module in transaction SE37 and checking its attributes.
  Reassign Function Module: If the function module is not in the correct function group, you may need to reassign it. This can be done by creating a new function module in the correct function group and copying the code over.
  Transport Request: If the function module was transported incorrectly, check the transport request to ensure that all necessary objects were included. You may need to re-transport the function module.
  Check for Naming Conflicts: Ensure that there are no naming conflicts with other function modules or function groups that could be causing the issue.
  Debugging: If the issue persists, consider debugging the code to identify where the function is being called and what parameters are being passed.
