SA release creation date Schedule line date

Firm zone: (go-ahead for production)

If the date of a schedule line lies within the firm zone, the vendor has the go-ahead to produce the relevant quantity with the assurance that the orderer will bear any and all material and production costs associated with the scheduled quantity in the event of subsequent cancellation by the latter.

Trade-off zone: (go-ahead for procurement of input materials)

If the date of a schedule line lies within the trade-off zone, the vendor has the go-ahead to purchase any input materials necessary to produce the scheduled quantity. The orderer will recompense him in full for such outlay (but not for any other production costs) in the event that he should subsequently cancel the scheduled quantity.

Schedule lines that lie beyond the firm and trade-off zones fall within the planning zone (forecast zone) and are for rough guidance only, being without any commitment on the part of the orderer.


  1. In the "Firm zone" field, enter the number of calendar days (calculated from the SA release creation date) after which the firm zone ends and the trade-off zone begins.
  2. In the "Trade-off zone" field, enter the number of calendar days (calculated from the SA release creation date) after which the trade-off zone ends.


If the firm zone ends in one month, enter 30 in the "Firm zone" field.

If the trade-off zone ends one month after the firm zone, enter 60 in the "Trade-off zone" field.


In the standard system, the end date for production go-ahead is calculated at the time of SA release creation from the firm zone. The end date for material go-ahead is calculated from the trade-off zone. These dates are displayed in the header of the relevant scheduling agreement release.

When an SA release is transmitted to the vendor via IDoc, the end dates for production and material go-ahead are determined from the firm and trade-off zones and the SA release creation date. These dates are shown in the sales scheduling agreement in the SA release header in the relevant fields (End of Production Go-Ahead, End of Material Go-Ahead).
