Because you have no safety stock, MRP will not suggest a purchase
requisition or planned order until your available quantity goes negative.
As I understand it, MRP would back off the Planned Delivery Time (MRP2)
and Goods Receipt Processing Time (MRP2) to calculate the release date of
the purchase requisition or planned order. In your example, adding a
safety time of 5 (workdays) would pull the release date in from Week 4 to
Week 3.

Subject: MRP type PD, safety time

Hello everyone,

I have a question concerning MRP type PD (MRP). Does SAP consider delivery lead time when it releases a procurement proposal for material?

For example, lets say that you have a material with delivery lead time = 2 weeks and safety stock set to 0. You have released sales & planned orders for, say 9 weeks in the schedule with the first 3 weeks frozen, and SAP calculates that, with today's production plan, you will reach a zero stock level in 6 weeks. Does it release a procurement proposal TODAY or in week 4 (because the lead time is 2 weeks)? If the latter case is true, is there a way to set a safety time so that it releases a procurement proposal in, for example, week 3?

Best Regards,
Ed
