Product: Transaction Manager
While some Trading Partners only require one version type for their transactions, others might have two or more choices. If you want to see what's available, take the following steps:
Click the Navigation Menu icon and select Trading Partners under the Transaction Manager menu.
Select the Trading Partner.
In the Action Bar, select Preferences, and choose Transactions.
In this view, you'll be able to see all mapped transactions for the selected Trading Partner, as well as the version.
If there are multiple options and you only want to see a select few, you can learn how to activate/deactivate transactions here.
