How to Model Buyer Managed Transportation for Shipment Delays in Planning

Summary:

I have a scenario where the Buyer is facilitating the Transportation of Goods from the supplier. As the PO is enabled for Buyer managed Transportation, it does not allow us to capture Delivery days as per design.

The requirement here is to capture the Delay delivery date in PO and use it in Planning to determine the various attributes that could be affected due to the delay in shipment delivery.

Content (required):

PO enabled with Buyer Managed Transportation.

Requested Ship Date: 03/Oct/2022

Promised Ship date: 04/Oct/2022

Requested Delivery date: 05/Oct/2022

Estimated delivery date (given by OTM): 10/Oct/2022.

Which attribute can be used in PO to store the Delayed Delivery date given by OTM/3PA(web Services are used to retrieve the Date from OTM to Procurement)?
