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?
