How To Fix FL623 - A move of function module &1 is not supported

FL623 - Overview

• Message type: E = Error

• Message class: FL - Function Builder messages

• Message number: 623

• Message text: A move of function module &1 is not supported

What causes this issue?

Moves of a function module into another function group are not supported
by Note Assistant.
Reorganizations of SAP function groups can be delivered only in SAP
support packages or in system upgrades.
<ZH>Background:</>
Note Assistant (SNOTE) does not support moves of function modules.
Manual moves of SAP function modules are blocked by Function Builder if
any modifications or older note corrections to the module exist in the
system.
Moves of SAP function modules in customer systems risk making imports of
SAP support packages impossible.
The transport tool R3TRANS ends the import with ?return code: ===> 8? if
the delivered function group and the include number do not match the
function group and include number in the target system. This problem
occurs when a delivery contains the moved function module as a
standalone object (LIMU FUNC) and the full affected function groups
(R3TR FUGR <(><<)>old function group> and R3TR FUGR <(><<)>new function
group>) are not delivered.
