Deleted Group Assets' Dep.Area -Urgent

Hi all of you..

In my testing client unfortunately i have deleted the depreciation area 15 which was assigned to Group Assets. In asset master also the group assets have been assigned under 15 only..and the same request has been transported to production client also..

Values have been posted to Group assets through assets.

After the deletion of the area 15 iam not getting the values of group assets.

After that i have created the area 15 and was assigned to Group assets , even now also iam not getting the values and i encountered with an error saying " no dep. area for the (group) asset ".
