Hi Experts,

I am having two PO lines in my Purchase Order#123.

PO Line 1: 1200 Natural Account: 15120

PO Line 2: 0.00 Natural Account: 56005

When i create PO matched invoice and when i try to add Freight line and allocate the freight line to PO line 2 having zero amount(Freight line should take the PO Line 2 Natural Account) getting error message that cannot allocate to PO line having zero amount.

Could you please help me, do we have any profile options to enable the allocate button to apply for PO lines having zero amount.
