3333701 - User exit not called even if you placed custom code into it via SE37

You have a certain user exit into which you coded custom ABAP code to influence a certain SAP business document processing logic.
Eventhough you have the code in the exit and the exit seems to be activated at SE37 tcode, the calling of the custom code not happens, the custom code not runs when it should.

For example user exit EXIT_SAPLMEREQ_010 and EXIT_SAPLMEREQ_008 are not called in ME51N even if it's active.
