Hi Experts,

I must input serial number on some items of purhcase order line, When I use direct deliveries funtionality for these items, The FSC standard procdeure is I must create sales order first and then FSC create a purchase order for me.

In this scenario, I can not update serial number on purchase order line for these items, due to sales order line already marking this purchase order. no change allow for these. I must input serial number on sales order line for my requirement.

But I must wait the item be delivered by supplier and get its serial number at that time. so does any method to let me input serial number on purchase order when I use direct deliveries?

Thank you

Ethan

Is the Serial number field on the direct delivery PO grayed out for you under Products > Tracking dimensions > Serial numbers?

On my screen, it is enabled. If you already have the serial numbers in advance, you can enter them directly in that field. Alternatively, you can register the serial numbers through Update line > Registration as well.

Hi Ethan,
In Microsoft Dynamics 365 F&Os, while using Direct delivery process.
When you create:
Sales order ->Use Direct delivery->System auto-creates and marks a Purchase order
The sales line and purchase line are hard-linked (marked).

Because of that:
You cannot change inventory dimensions (including Serial number) on the PO line.
The serial number must follow the sales line dimension. The marking prevents modifications.

In Direct delivery, the sales order drives the transaction and the PO is subordinate.
Inventory dimensions (including Serial number if active) are controlled by the sales line.
Since the serial number is part of the inventory dimension, it cannot be updated independently on the purchase order once marking exists.

Recommendation:
Use Serial Number at Product Receipt
When the supplier delivers:
Go to Purchase Order ->Click Product receipt
In the Posting form → Lines
Click Inventory → Dimensions
Enter the Serial number -> Click Post
The system will:
Assign the serial number at receipt
Automatically update the linked sales order transaction
You do NOT need to pre-enter serial number on sales order.

I have tried this in my scenario. Update -> Registration is also one of the approach that can be used.
