Message text: There are gaps in the profit center's period of validity

What causes this issue?

The profit center that you are editing contains gaps in its period of
validity.
Example: the profit center is valid from 1 Jan. 2000 to 31 Dec, 2000
and from 01 Jan. 2010 to 31 Dec. 2010.
A new master data maintenance procedure has been in effect since
Release 4.6C. As a consequence, gaps in a profit center's period of
validity are no longer possible.

System Response

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?

You can only continue processing the profit center in display mode. To
change existing profit centers with gaps in their period of validity,
you must convert to the new procedure. You do this in Customizing for
Profit Center Accounting, under <ZH><ZK>Tools -> Convert Master Data to
Release 4.6C</></>.
You can still post to profit centers which have gaps in their period of
validity. The conversion is only necessary when you maintain master
data.
