The principle is to have an object – the scheduling agreement – with a target quantity and the corresponding conditions, to schedule receipts as “calendar lines” (according to purchase requests) and to send orders – “releases” to the supplier with reference to the planning agreement. Versions are created for a defined horizon and updated at defined intervals. In addition to operational approvals, it is possible to send forward approvals to the supplier to inform them of anticipated future needs. Thus, the scheduling agreement is an object that supports cooperation with the supplier. One of the problems we faced when creating an SAP planning agreement was that we had a currency gap. We went to this transaction (OB08) and introduced currency conversion.
