Hello,
I am creating a Business Event to update the External Ref Number field on the “Import Bank Transactions” form.

I have created an Import Scenario as the subscriber, and the mapping is as below.

For the testing purpose, I entered an action on the screen and perform the action manually. But it gives me the below error.

But the scenario works and update the external number when I execute it manually.

Is there’s a way that I can, correct?
Thank You
