Arithmetic overflow error

Hello, we have been using ARAS for a while now and recently in Project management we have ran into an error: Overflow error in the SUM of the total hours in the "1332 PROJECT NAME" Work Breakdown Structure. The rollup_actual_work property does not allow the SUM of all Activity Time Records to be greater than it's precision. in SQL: exec activity_status_rollup 'E251EE221C4C4FFC8CAE120709DE55B0','E. Europe Standard Time' To solve the issue we have tried to increase precision of decimal  under property rollup_actual_work in itemtype Activity2. This has only caused a new error. Arithmetic overflow error converting numeric to data type numeric. The statement has been terminated. in SQL: exec activity_status_rollup 'E251EE221C4C4FFC8CAE120709DE55B0','E. Europe Standard Time' Has anyone ran into such a problem and know how to fix this? thank you
