Allocation Effective Dating - Group vs. Step

When initially building allocation groups, the effective date is typically set to 01/01/1901 and similar for steps. Throughout the lifecycle of the allocation updates are made to the steps changing the associated effective date, but not changing the group effective date.

On occasion, steps are added or removed and a new group effective date is added to reflect the addition/subtraction.

We are updating from 9.0 to 9,2 and finding that changing the group effective date is giving an error. 'Allocation Step XXXXXXX effective date is greater than group effective date. (5060,211) Allocation Group cannot be saved until the error is corrected.'

This makes no sense since the allocation worked before saving.
