Product: Transaction Manager
By default, the Item Catalog automatically fills in with item information when you receive incoming Purchase Orders. However, you do have the option to remove this setting. Either way, the setting can be managed within the Trading Partner profile in Transaction Manager.
Click the Navigation Menu icon in the upper left hand corner, and select Trading Partners under Transaction Manager.
Select the Trading Partner from the list.
In the Action Bar, click Settings.
Under Automatic List Updating, you can either check or uncheck the box that enables the Item Catalog to be automatically populated.
If changes are made, click Save in the Action Bar.
