equirement, a firmed receipt exists, which can be used to cover this requirement. Then<br />

the system displays a rescheduling date as well as the exception message Bring process<br />

forward for this receipt. The net requirements calculation then uses this receipt and the<br />

system will only create another procurement proposal if the receipt quantity is not<br />

sufficient to cover the complete requirement. Several firmed receipts can be used to cover<br />

one requirement.<br />

The rescheduling horizon is always calculated from the MRP date.<br />

Postpone process (reschedule out), or cancel process<br />

The net requirements calculation checks over the complete time axis whether availability<br />

could still be guaranteed without the receipt in question. If this is the case, the system<br />

checks whether the receipt planned here could be used to cover a future requirement. If<br />

the system can find such a requirement, it then displays a rescheduling date as well as the<br />

exception message Postpone process for this receipt.<br />

If the system finds no future requirement, for which the receipt is required, the system<br />

displays the exception message Cancel process.<br />

Do you have a <strong>SAP</strong> PP Question?<br />

Schedule Margin Key in <strong>Production</strong> Scheduling<br />

I want to know impact of schedule margine key in production scheduling in<br />

following changes in mateial master<br />

1) if I have schedule key where all floats are zero but I enter in-house prodution time<br />

as e.g. 7 days .<br />

2) if I have key where floats before prodution is 5 days and same values in next<br />

floats and in house production time as 1 day.<br />

All above with MTO what is impact of above cases in scheduling.<br />

While "Basic Scheduling" in MRP... Scheduling margin key is not considered. It takes the<br />

"In house production" days for fixing up the start date. This is only exact to "days".<br />

Lead Time scheduling is carried out on request from the scope of MRP. Target dates are<br />

calculated from routing and Capacity requirement calculations are also done. The<br />

calculations are exact to the seconds (time).<br />

SCHEDULING MARGIN KEY takes effect only for Lead Time Scheduling. For this you<br />

have to configure for "scheduling horizon" to limit the period for which lead time<br />

scheduling and capacity planning should be carried out. scheduling horizon is the period<br />

in working days. If a planned order has its basic start date within this period in future,<br />

lead time scheduling is carried out using the selected routing. The production times are<br />

calculated from the float times of the scheduling margin key in the material master record<br />

and the time from the individual operations. If the planned order has its basic start date
