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.
