You probably already figured this out given the date of your post, but since I did not see it in the thread anywhere, the most common Service Manager error you will receive is because the required fields on the form do not have data in them (which they would not initially after the form generation from the IMG). If you fill in any required details for the form you are testing, save that and use the filled in form to test, you should get past this error.
I have this same issue. My configuration seems fine, and the inbound form can be viewed in SOIN so obviously it has been received, yet it does not create the workflow, even though the very same form tested okay in program R_EHHSS_TEST_FORM_INBOUND.
I have activated the trace in SOIN, and have the same problem as Irene (no exit found despite the configuration appearing to be correct). The solution to this problem has not yet been shared in this thread.
Anyone solve the missing exit scenario?
