Cost centre-/cost unit groups - double definitions
(available from V6.4.814)

Cost accounting -> Basic data -> Cost centre groups, Cost unit groups

Now you are able to check double definition of cost centre/cost unit inside of cost unit groups/cost centre gruops with "Edit -> Check double definitions".

The program executes this check, if you close the window, automatically.

If double definitions are found, you will get a protocol on the screen.
