You are using a Product with a List Price maintained in Purchase Order XXX (XXX represents the Purchase Order ID).
Upon creating of the Purchase Order with this Product, the Price is automatically maintained.
However, this Price is editable.
Reproducing the Issue
- Go to Purchase Requests and Orders work center.
- Go to Purchase Orders view.
- Show All Purchase Orders.
- Find XXX.
- Select Edit.
- Select View All.
- Go to the Items tab.
You can see here that the Price information is editable.
This is expected system behaviour. Users responsible for processing Purchase Orders should have the authority to change the price in the document if it is required.
You can create a PDI solution to prevent the Price from being changed.
