Adding Invoices to Deliveries query

Experts,

I have a query that I want to populate with Invoice details too. This one is listing all the Deliveries and details that was entered on a Service Call Expenses tab.

I get no data back with this query.

SELECTDISTINCT T0.[callID], T1.[DocPstDate], T1.[DocNumber], T5.[DocNumber], T1.[Object], T0.[custmrName], T3.[ItemCode], T3.[Dscription], T8.[Name], T3.[Quantity], T3.[Price], T0.[internalSN] as'Eng S/N'

FROM OSCL T0 INNERJOIN SCL4 T1 ON T0.[callID] = T1.[SrcvCallID]

INNERJOIN ODLN T2 ON T1.[DocNumber] = T2.[DocNum]

INNERJOIN DLN1 T3 ON T2.[DocEntry] = T3.[DocEntry]

INNERJOIN OINV T5 ON T1.[DocNumber] = T5.[DocNum]

INNERJOIN INV1 T6 ON T2.[DocEntry] = T6.[DocEntry]

INNERJOIN OITM T4 ON T0.[itemCode] = T4.[ItemCode]

INNERJOIN OCTR T7 ON T0.[contractID] = T7.[ContractID]

INNERJOIN OSCP T8 ON T0.[problemTyp] = T8.[prblmTypID]

WHERE T3.[Price] > 0

Any help would be greatly appreciated,

Marli
