I wouldn't store anything. Just set up your checks in Dynamic Calc accounts or UDs, so that those accounts will return 0 or 1 when the check is passed or not; bring the accounts in your cube view (replacing your previous stuff), then use GetDataCell in your Confirmation Rules to simply retrieve that value. If the name of the account or UD is self explanatory (e.g. PositiveBalanceCheck), simply returning that as description of the error should be enough of a clue to figure out what should be corrected.
In this way you've written your check once, in one place, and reference it from both CV and ConfRules.
