mrp question

Hi,

Following is the requirement :

1. we want to schedule the work orders one day or 2 days before the schedule ship date.

For example, Schedule ship date is 20-08-2014 23:59:00, now MRP is suggesting completion 20-08-2014 00:00:00 and work order completion date is 20-08-2014. The requirement is that the completion date should be 19-08-2014 00:00:00.

2. Can we setup MRP such that it considers Sales Order request date for planning instead of schedule ship date.

Regards

Rajiv
