Manged system / update roles problem

Hi experts.

Last week i just installed the newest SPS on Solman 71. Everything works fine since yesterday.

Yes, i went through the basic-configuration and everything is green.

Now, yesterday, the workcenter wants me to "update roles" for the RFCs in clients:

"New roles are needed on Managed System. To update roles, select the Option “update roles” for the RFCs in clients 010 "

-Please see also the attached image-

Or sometimes it says:

"You need to upload/update the roles for users SMB_SID (from RFC ...... [...])"

I cannot see a option "update roles". I can see an option under the users:

"Use Existing User, Specify Password and update of roles".

But in the past i choose the option:

"Generate User and Password" - so i cannot give a password and update the roles. I dont think that this is a good idea to change it manually.

So i deleted all infos over "Delete RFCs" and removed all RFCs and users.

After recreating it looks good, the assistant asked me to upload the new roles and in the overview in "Managed System Configuration" the RFC-Status is green. After a new look over "configure system", i get the message again, that i need to update the roles.

Whats up there? Could someone give me a tip?

It doesnt look nice:

I also get sometimes a message that the BACK_Destination doesnt exist. But it does - it works fine, too. On the other hand i recreated it and the light was green.. Strange!

My system:

Thanks in advance.
