I've created a project profile for statistical WBS elements. I've also created network profile (which calls external number ranges) for this project. When I create a project in CJ20N, I'm encountering some issues. There is no issues when creating WBS elements. But the problem is, when creating networks, I'm getting a message stating "Receiver categ. WBS is not allowed by settlement prof. 000090 for this sender". What do you think should be the issue?
