Create an own (Z*) Function-Module within an SAP-Owned Function-Group

[master1980]

Hello,

I want to create an own (Z*) Function-Module within an SAP-Owned Function-Group, Pros/Cons are not part of the Discussion.
The Function Group is M61Q.
I Created ZMD_BEARBEITEN_KOMPONENTEN as Copy of MD_BEARBEITEN_KOMPONENTEN
Within the INCLUDE LM61QUXX SAP add's automatically LM61QU20 as the ZMD_BEARBEITEN_KOMPONENTEN is the 20st Function-Module within the Function-Group.

Questions:
I was not asked for the access-key, so i think this is not a Modifikation? In the coding of ZMD_BEARBEITEN_KOMPONENTEN there's an "{ INSERT ...." Tag.
What is about changes by SAP within M61Q in the Future? Will ZMD_BEARBEITEN_KOMPONENTEN still be there after an Update? If SAP adds a new include LM61QU20 into the Group, will ZMD_BEARBEITEN_KOMPONENTEN then be in LM61QU21?

Many thanks

NEVER copy a standard function module, do a modification of the standard because you'll be informed by the upgrade process (SPAU). It has been discussed a lot in the forum in the past years, and the old way (copying standard) is now considered completely wrong.

NB: S/4HANA doesn't request access keys anymore, but anyway modifying anything standard is a modification of standard.

Thank you very much, I have also an R/3 System here and testwise I tryed to copy the FM there, I was asked for an Access-Key. I will set up a meeting with the customer and will gofor the modifikation withing the SAP-FM.

Actually I have been set on the wrong track when I copied the FM in S/4 and not beeing asked for the access key by falsely thinking copying is not not a modification.

According to the Mandalorian: This is the way!
