We are getting the error:
Error invoke: on an integration that is invoking a B2B service from the Enterprise Server. We have this integration working in our system test environment but when we migrated it to the next QA system, we get this error. The userid and password is valid. Any Ideas?

Doble check your ACL assignment for the service. ACL mappings don’t travel with the package. They are stored in the aclmap_sm.cnf file.
