Managed Customer Service Error ALREADY_MANAGED_FOR_UI_ACCESS

[fischi]

Hello!

In our AdwordsAPI Tool we use the Managed Customer Service to link Accounts to MCCs.

So far so good, usually it is no Problem at all (except the duplicate Child issue, but there is no way of solving that directly).

Today, a strange Error appeared - ALREADY_MANAGED_FOR_UI_ACCESS, and I have no Idea, what this is supposed to mean, as there is no description in the response, and google search can't find this message anywhere in the internet. Even in the documentation, (Version 201409 - our production version, and Version 201502) there is no mentioning of this error.

Can someone please help me to get a grasp on this? Or explain what that is supposed to mean?

If you need any more information or explaining of the situation, please ask, I can provide every bit of information related to the problem, but the operation itself is rather straight forward.

Hi,

you try to link a MCC that is already linked by another MCC:

A manager account can't be directly managed by more than 1 other manager account.[1]
