E8.1 Partial voucher match


VIP Member
How can we make partial voucher match to full receipt.
For example,

In order, qty ordered: 15, total amount: 3,000.00
In receipt, qty received: 15, total amount: 3,000.00
Now, I want to make a voucher-match for the amount 1,500.00. But I cannot touch the quantity, because I cannot use fraction in the quantity field.
I have tried in DV, but when I created the voucher, the remaining 1,500.00 going to cost variance, and the whole receipt is matched.
