Hi Leonardo,
First of all you have not maintained any clearing criteria in OB74? Here you have to maintain the field ZUONR or other fields which are common in both line items. However, as per your screen shot you are trying to clear the invoice document with advance. You cannot do automatic clearing for them in F.13. If you want to clear them, then first you do configuration in OB74 properly, then after do down payment clearing in F-39, after do automatic clearing in F.13.

Mukthar
