I want to use SD down payment process and all standard settings for Item Categories, condition types, pricing procedures and billing plan have been done.
first of all I have created down payment request as a billing plan item, then I cleared the accounting document by F-29 transaction.
the next step is creating first partially invoice, but the cleared down payment did not appear in invoice as second line item.
I have checked all related settings that I know.
Can anyone tell where is the problem?
