Down Payment Clearing in MIRO

Dear Team,

In PO, there as two Line Item i.e. 10 & 20.

Since Down Payment can not be done at Header level, all down payments are done with PO Line Item 010 as reference. At time of Vendor Invoicing for 020, Down Payment (which are made against 010) is not visible for Clearing.

Please advise us how down payment can be cleared..

Regards,
