The procedure using the source list is similar to the procedure with standard purchase orders or with scheduling agreements. The only difference is that the system reads the source list to determine the source of supply. The vendor or the outline agreement (scheduling agreement, quantity/value contract) is recorded in the source list.
The entry cannot be relevant to MRP for scheduling agreements with the KANBAN indicator. Moreover, only one entry is allowed so that the scheduling agreement can be specifically identified in KANBAN procedures.
