I have come across this situation earlier, did some settings in SLD ..tech system...(Don rembr it nw....)
I am not able to see the list of interfaces for an ECC Bus.System during Interface determination,
I manually have to key in the name of the BAPI instead of the values appearing in the value list....
I am sure that the is something missing while havin created the BS and TS in the SLD,
Can someone guide me what my approach would be.
Replies much appreciated. Thanks
