Get advances payments

Hello
I have advance payment and i am trying to get it in an invoice but the save button did not appear i do not know why!!
Although the balance of the customer who paid the advances is right so how i can solve this
thanks a lot

How did you take the advance? Payment entry or JV? Did you try to fetch the advance payment in to the sales invoice by using the get advance button?
