Enterprise organization active in controlling area &

What causes this issue?

You want to edit the standard hierarchy (or parts of it) in controlling
area &V1&. However, the enterprise organization is active in this
controlling area, meaning that the standard hierarchy is derived from
the enterprise organization and <LS>cannot</> therefore be manually
maintained.
For this reason, the standard hierarchy can be <ZH>displayed</> only,
with the exception of the <LS>report information</> on the cost center
groups or profit center groups. You can still enter this on the detail
screen of the <ZH>new maintenance interface</>.
This data is retained when you generate the standard hierarchy from the
enterprise organization.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Maintain the enterprise organization and generate the changed standard
hierarchy as follows:
From the Cost Center Accounting or Profit Center Accounting menu,
choose <LS>Master data -> Enterprise organization -> Change</>.
In Customizing for Cost Center Accounting or Profit Center Accounting
choose <LS>Enterprise Organization -> <DS:SIMG.COOMCCA_KEOG_DC>Generate
Standard or Alternative Hierarchy From Enterprise Organization</></>.
