Exceptions that modify the planned finish date

After the finish date is calculated, these exceptions can modify the planned finish date and move the date forward or backwards in time:

The time fence is taken into account during order planning generation. The time fence can move the finish date forward.
The finish date of the last firm planned or actual order can move the date forward.
Fixed delivery moments can move the finish date backwards.

The following sections discuss each of these situations.

Time fence

If the Generate within check box is cleared in the Generate Order Planning (cprrp1210m000) session, order planning recognizes the requirements within the time fence, but shifts the requirements to the end of the time fence.

In other words, if the Generate within check box is cleared, the requirement dates always fall beyond the time fence. If the finish date is offset within the time fence, the finish date is moved forward to the time fence date, consuming the subsequent lead times.

If the requirement date equals the time fence date, all four lead-time components are consumed.

In the previous example, a warning is given that the finish date is too late for planning extra lead time and safety time.

Firm planned or actual orders

If the Planned Order before Firm/Actual check box is cleared in the Planning Parameters (cprpd0100m000) session, no planned orders can finish before any actual or firm planned order is finished. Therefore, the finish date of the planned order is moved forward to the finish date of the last firm planned order.

Note: In the following figures, Enterprise Planning offset refers to the offset of the requirements date to the planned finish date. The Enterprise Planning offset includes outbound time, inbound time, safety time, and extra lead time.

All orders, finish date corrected for firm/actual

If the Planned Order before Firm/Actual check box is cleared, the finish date is moved forward in the same way as when a time fence is involved. A planned Purchase order is not planned before actual purchase orders and firm planned purchase orders. A planned Job Shop order is not planned before JSC production orders and firm planned production orders.

Note: The correction applies only to planned production orders and planned purchase, not to planned distribution orders.

Fixed deliveries

A plan item can be linked to a fixed delivery code. A fixed delivery code is used for order planning based on fixed delivery moments. If fixed deliveries are set up for the item, Enterprise Planning moves the calculated finish date backwards to find the nearest fixed delivery moment.

You can specify fixed delivery codes in the Fixed Delivery Codes (cprpd2110m000) session.

All orders, finish date set to fixed delivery
