Which dates in Purchase orders refer to "Old due date date "

Summary:

Hi,

Which dates in Purchase orders refer to "Old due date date & Suggested due date" in planning. 

In planning under Material Plan pivot table, we have a scheduled receipts measure. The scheduled receipts measure will show the purchase orders on basis of "old due date" but we want to know how this old due date is collected.

We want this as per purchase order not planned order old due date calculation

Thanks,

Sangeetha
