Hello,
MRP is not using the promised date on the PO’s line item.
It is using the date in the top summary area.
Here is the PO. The line item promised dates are much farther out than 10/31/22.
Here is what MRP shows in the detail inquiry. It is using the 10/31 date from the image above.
We have confirmed changing the header date changes the date on the detail inquiry.
