Shaik,
You will not get RF'x number in SC DS.
RF'x DS is 0BBP_TD_BID_1
It has,
BID_NUMBER | Order number | CRMD_ORDERADM_H | OBJECT_ID |
You may need to enhance your SC DS .Findout the RFx for each SC at the backend tables with the help of your functional guys.
Try to find the SC and its relevant RF'x with the GUID, you have to talk to functional guys to understand more how the RFx's are captured for SC's.
I dont have SRM system now, sorry i cannot help you much without seeing system.
Thanks...
