RE: Pop-up/Information on item/product in Purchase order
I do not completely understand your first line, but this is what I have inferred:
You are looking to create a notification when an item is added to the purchase order line and want to change the item details before sending the confirmed order through the EDI. Is that correct?
On the Product(Master data) table [DMFProductMasterEntity], you will have a denormalised view of data fields, from other tables; for example inventory dimension group, storage dimension group etc. which drives the functionality for example physical and financial posting. This type of information you cannot see on the purchase order line.
Some of the information like purchase price can be seen on the purchase order line when you select an item defined with it.
Other than that, the underlying database schema can only be modified through a customisation in the AOT to display information on the purchase order line
You can look at creating alerts and trigger them when, for example, a purchase order is created, modify the order information before sending it through EDI. The alerts might cause some delay; I have seen some delay while using alerts in some of the implementation projects I have done.
Have a look at the below link:
docs.microsoft.com/.../managing-alerts
Note: The alerts rules setup will be dependent on your requirement and the trigger you want to set before sending out through the EDI.
You can look at purchase order approval workflow
