I got below error while posting check reversal.
Do you have the value for Branch dimension on the voucher related to that check (that you are trying to cancel)?
Does that account structure is modified after posting that check?
yes, Voucher has financial dimensions. Account structure not modified.
i have backup before GST patch, in that same entry got posted. after gst error is coming.
But, this is not related to GST.
Do you see the branch dimension filled on check reversal journal?
