I ran into the same problem last week. In regards to the āConcurrent Web Services User checkboxā, I donāt think this exists anymore. It use to exist years ago and some of our really old employee records still have it, but they are really old. I recall that NetSuite did away with this checkbox when they implemented SuiteCloud Plus licenses.
Another developer posted a solution on how to get around the issue. Iāll find it and post it.
