Cannot create user groups from scoped application

[Maik Skoddow]

At my scoped application I want to create user groups via a business rule. 

I checked  "create" and "update" at Table "sys_user_group":

And I added cross scope priviledges:

But it's still not possible to create user groups:

Does anyone have any idea what I might have forgotten?

I did notice that, did you try the web access checkbox as well? I see it trying to use the web api method?  One other check is the user that was created for this activity.

Hi everyboy,

Thank you very much for your hints and the links to further information. I have learned a lot.

After refreshing my PDI and starting from scratch, it now works as intended. I have no idea what went wrong.
