receiving PO system throws an error “The transactions on voucher do not balance as per XXXXX

I had same issue but it was related to PO when on receiving PO system throws an error “The transactions on voucher  do not balance as per XXXXX. (accounting currency: xxxxxx - reporting currency: xxxxxx).

I fixed this by assigning an account to Purchase Accruals in Inventory & Warehouse > Setup > Posting > Profiles then Purchase Order
