How To Fix KT189 - The period intervals overlap

KT189 - Overview

• Message type: E = Error

• Message class: KT - RK Message Table Maintenance

• Message number: 189

• Message text: The period intervals overlap

What causes this issue?

The period intervals overlap for the entries with
Controlling area = &V1&,
Fiscal year = &V2& and
Cost element = &V3&
This is not permitted.

How can this happen?

If two rows are identical apart from the period interval and the
percentage, such as
000 AAAA yyyy 420000 09 12 10.0
000 AAAA yyyy 420000 11 12 5.0
the period intervals (09,12) and (11,12) must not be joined.
This means: No value from one interval is allowed to appear
simultaneously in the other interval. The error here has occurred becaus
e of an overlap. Periods 11 and 12 appear in both intervals.

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?

Correct your entries so that the period intervals that contain the same
controlling area, fiscal year, and cost element are disjoint.
