Cannot assign dataprep user to a dataprep group

[Anonymous]

Hi,
I'm trying to add data prep users to a data prep group in the tac. (at first we didn't have any roles as wel, solved in this topic)
But the pick list is empty.
The groups are created:

The table usergroup (SELECT * FROM tac.usergroup) is filled.
table usergroup_user = empty
table user_usergroup = empty
Is there a fix possible?
Version TAC: 6.2.1 (upgraded from 6.1.1(Manual installation))

Hi,
Are your  Data Prep users with  DataPrep  access right only?
Have you already checked this jira issue?  https://jira.talendforge.org/browse/TMC-718(point 2)
I f user has DP option, user can be added to DP group.
Best regards

Hi,
Thanks for the reply. I removed the other rights from the users and only than it's possible to assign users to the DP groups.
So I have to set the type to "No Project Access", than it works.
Why is the combination not possible? Can you tell me the idea behind it?
Thx
Taco
