Integration Manager error when running a Sales Order Processing integration

Microsoft Dynamics GPI created an integration recently using Integration Manager for a client to import sales invoices into Microsoft Dynamics GP. It worked fine when I was developing it, logged in as DYNSA, and for one of the finance teams managers, but produced an error for the user:

I toggled the Integration Manager ini file parameters so I could see what was happening with the windows to get an indication of the problem. The first window opened was Sales Order Processing Setup; why tis opened I’m not sure, but the user didn’t have permissions for this window. I did a quick test by copying the users security to a test account and added access to that window and the integration ran through without a problem.

This seems to be an operating as designed thing, but it seems odd that the SOP Setup window needs access.
