since SRM day-1 Japan use sourcing cockpit for their procurement which meant after SC created, it will park to the buyer sourcing cockpit to convert the SC become Bid or master contract, let's focus on this master contract....this master contract end result will become a contract in ECC(can be viewed by tcode ME33K) and later if there's any SC related with this master contract(check by material grp), after SC was created, it will not send to sourcing cockpit but become auto PO instead
