When you open a purchase order or a purchase quote in Microsoft Dynamics 365 Business Central, you normally cannot see what kind of correspondence you have had with your vendor about that order. You cannot tell whether you originally asked for a quantity of 20 on an item, or whether you wanted a different number. Purchase Order Management solves this by letting you track every change on each purchase line, so you always have the full history of what you and your vendor agreed on.
With Purchase Order Management you can see the requests you sent, the answers your vendor gave, and which quantities, prices, and delivery dates were accepted or rejected. You find this history in the archived purchase lines. Instead of digging through emails, phone calls, or chat messages, you read the full negotiation directly on the purchase line.
You can also use the change history for controlling, for example to check whether a vendor consistently tries to change prices or delivery dates after you place an order.
Tracking changes on each purchase line
The change tracking lives in the archived purchase lines. When you open a specific line, you can dive into its historical transactions and see exactly what has happened on the order from the first request to the final agreement.
Each transaction shows the three things that matter on the line: the quantity, the unit price, and the requested or promised receipt date. You can follow the back-and-forth between you and the vendor step by step.
A practical example of vendor negotiation history
The history reads like a log of the negotiation. In a typical case it looks like this:
- First request: You ask for 10 pieces at a given unit price and a requested receipt date.
- Vendor reply: The vendor accepts the quantity of 10 pieces and confirms a ship date, but does not yet confirm the direct unit cost. So the vendor answered two of the three things that matter on the line.
- Second request: You send a new request asking for a lower price, for example 6 dollars instead. The vendor rejects it.
- Third request: You change your request and offer to buy 20 pieces if the vendor can give you a price of 6.25.
- Vendor reply: The vendor accepts a quantity of 20, confirms the receipt date again, and confirms a direct unit cost of 6.28. You accept that.
When you go back to the purchase line, you end up with an order of 20 pieces at a direct unit cost of 6.28, with a promised receipt date of 10 December. The full historical track of how you got there stays attached to the line.
Why the change history is useful
The biggest benefit is that you no longer have to chase down emails, phone calls, or other messages to reconstruct what was agreed. You look directly at the line and read the correspondence between you and your vendor for that specific item.
It also gives you a basis for controlling. You can see whether a particular vendor always pushes to change prices or delivery dates, which helps you decide how to handle that relationship going forward.
Q&A
Can you see vendor correspondence on a standard purchase order in Business Central?
No. On a standard purchase order or purchase quote you cannot see the correspondence you have had with the vendor or what you originally requested. You need Purchase Order Management to track the changes on each line.
Where do you find the change history for a purchase line?
You find it in the archived purchase lines. From a specific line you can open its historical transactions and follow every request and reply between you and the vendor.
What details does the purchase line history track?
It tracks the three key values on each line: the quantity, the unit price (direct unit cost), and the requested or promised receipt date. You see what was requested, what was accepted, and what was rejected.
How can you use the change history for controlling?
You can use it to check whether a vendor consistently tries to change prices or delivery dates after an order is placed, which gives you a documented basis for managing that vendor relationship.
