Std Function Modules in Customer Namespace in ECC6?

Hi,

I am in ECC 6. In the system I see function modules with names starting with Y and Z. For eg Y_H_N2_01_CHCK_N2PS_2 and Z_ISU_DUNNING_EVENT_0303.

There are over 2000 such function modules. When I checked the tables TADIR and TRDIR couldnt find entries for these objects.

Also checked the attributes of these objects, and everywhere the Person Responsible and Last Changed by was SAP, including in the function group and function pool.

1) Is SAP creating objects in customer namespace, or am I missing something? or how does one know for sure whether it is a custom object or a standard object?

2) Why are these Function Modules not visible in TADIR or TRDIR?

Thanks,

Jayesh

    Hi,

    a quick answer :

    1) Is SAP creating objects in customer namespace, or am I missing something? or how does one know for sure whether it is a custom object or a standard object?

    Usually, you shouldn't call your function modules Z_ or Y_ because it's reserved by Sap. But for function modules it's non so mandatory as other ojects. Your function modules could begin with Z or ZZ or Z_.

    2) Why are these Function Modules not visible in TADIR or TRDIR?

    Because you have search for function group and non for function module name. I'm non on ECC 6.0 so in my system that FMs doesen't exist. But if you go on SE37 transaction. Then in the first tab (propierty) you can see the program name and the include name where the code function is implemented. Then you can search in TADIR with the name of the program

      Hi,

      The SAP naming Standards can be anything. say Z123 or ZABC.

      The Custom Naming Standards is to start with Z_ or Y_. (Underscore is a must).

      Z and Y are reserved for SAP only. So there are function module name with starts with Z and Y with uname SAP.

      Hope it got cleared.
