What causes this issue?

A period of time with &V1& period(s) was chosen for the standard
analysis. A quantity of &V2& was saved in the
exception definition for the time period.
This causes incorrect readings if data from the exception is based on
the number of periods that were noted there.
For example, an analysis with a threshold value of 40,000 DM and a
quantity of &V1& for the period will have completely different results
than with a quantity of &V2&.

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