Hi Bastian,
Thank you for the response, I really appreciate the help.
I tried your suggestion and changed the settings for the B1 Service atom, but I'm still getting the exact same result. I also tried to change the request keys and values to the same as you had in your example (UserCode, manager) and removed all other recipients.
The payload structure I used was the same as defined in the help. I generated the schema using the B1 service atom. The structure of my Atom19 is below. I've commented out all of the actual content to try and reduce the chance that something else in the atom was causing the error.
The debugging output shows the output of Atom19
I've spent a lot of time already trying to figure this out. If I can't get it to work, I'll probably remove the service call from the step completely and use a separate step for the error handling which isn't ideal here because I'm trying to handle multiple invoices separately without having to stop processing if there is an error.
If you have any other ideas, I'd love to try them out.
Regards
