Order Items Page Does Not Set Estimated Landed Cost on Purchase Order
Order Items Page, when used to create Purchase Orders, if the item is configured with the Estimated Landed Cost configuration, that field does not auto populate on the Purchase Order line for that item.
There is an enhancement request: 461632 for this specific issue.
If you manually create the Purchase Order, the Estimated Landed Cost template does pull into the Purchase Order line.
This issue has been around for a long time. Without this working as designed, it makes it very difficult for someone who using any method of planning that wants to create PO's from Order Items page go through and remember to do this step before the PO is Received.
