• Message number: 630

• Message text: Interval is within other interval, a true demarcation does not exist

What causes this issue?

The intervals (&V1& &V2&) and (&V3& &V4&) are not permitted. One of the
intervals is not actually contained in the other interval because its
upper or lower limit falls on the upper or lower limit of the other.
This means that the smaller interval is not truely demarcated within
the larger interval. A true demarcation must be maintained.

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?

Change the upper and lower limits of the intervals so that the upper
and lower limit of the smaller interval are not the same as the upper
and lower limit of the larger interval.
