Hi Kshitiz,
SFC value is just an ME’s internal identifier for the production unit, it has nothing to do with serial numbers that are generated in ERP. The link between ERP serial numbers and SFCs is kept only in SHOP_ORDER_SFC_PLAN table, which is designed to define the planned SFC ID's that should be released with this order.
Therefore, SFC numbers are normally not required on ERP side.
