Can you assign multiple G/L accounts in the Purchase order for the same line item?

Yes, we can assign multiple G/L accounts in the Purchase order for the
same line item. The costs can be allocated on a percentage or quantity
basis. If the partial goods receipt and partial invoice receipt has already
taken place, then the partial invoice amount can be distributed
proportionally, i.e. evenly among the account assigned items of a
Purchase order. Alternatively the partial invoice amount can be
distributed on a progressive fill-up basis, i.e. the invoiced amount is
allocated to the individual account assignment items one after the other.
