Link betwwn a/p and a/p down payment

Question

i am creating a balance sheet report for vendor for that i want each  and every field like down payment amt,applied amt n bal due amt etc.
but i didn't get the linking between a/p invoice and a/p down payment invoice.
ex. for vendor V101 i have created an a/p down payment invoice for 50000
    agn i have created same amt a/p down payment invoice
after that i have created an a/p invoice for 30000 i used amt from down payment
i want the sum of total down payment for that vendor according to that i want to calculate the remaining bal.
like total is 100000 for down payment .
as well as i want a/p invoice in which i am not used that down payment amt.
means i want both condition downpayment amt used in a/p invoice and without used downpayment a/p invoice.
can any one help

Hi,
Try this query :
SELECT 
     FROM dbo.ODPO T0
     INNER JOIN dbo.DPO1 T1 ON (T0.DocEntry = T1.DocEntry)
     LEFT OUTER JOIN dbo.PCH9 T2 ON (T1.DocEntry = T2.BaseAbs)
     LEFT OUTER JOIN dbo.OPCH T3 ON (T2.DocEntry = T3.DocEntry)
     LEFT OUTER JOIN dbo.PCH1 T4 ON (T3.DocEntry = T4.DocEntry)
This link is from AP Downpayment, AP Invoince. Since you are asking for AP Invoice to Ap Downpayment
just  reverse the link above.
Thanks.
