Can you please explain in detail exactly what you are doing and if you are working with a script, post the script.

Can you post the relevant portion of your code? From your post it is not clear what language or methods you are using to execute the code.

i am trying to build a 3rd party application using c# to read sales order and create a xml ,

and i have also added the sample code that i am using

*********************************************************************************************************************************************
*********************************************************************************************************************************************

OrderLineObject.nGetResultSets("QuantityOrdered$", "UnitOfMeasure$", Quantity, PointOfTitleTransfer,
"SalesOrderNo$ = " & Chr(34) & SONumber & Chr(34) & " AND LineKey$=" &
Chr(34) & Snumber(i) & Chr(34), "", "")
Qunt = (Split(Mid(Quantity, 3, Len(Quantity) - 3), Chr(138)))
POT = (Split(Mid(PointOfTitleTransfer, 3, Len(PointOfTitleTransfer) - 3), Chr(138)))


'If Not (CBool(OrderLineObject.nSetKeyValue("SalesOrderNo$", SONumber))) Then MsgBox(OrderLineObject.sLastErrorMsg)
'If Not (CBool(OrderLineObject.nSetKeyValue("LineSeqNo$",lineseq(i)))) Then MsgBox(OrderLineObject.sLastErrorMsg)
'If Not (CBool(OrderLineObject.nSetKeyValue("LineKey$", Snumber(i)))) Then MsgBox(OrderLineObject.sLastErrorMsg)
'If Not (CBool(OrderLineObject.oLines.nSetKey(Onumber(0)+lineseq(i)+Snumber(i)))) Then MsgBox(OrderLineObject.sLastErrorMsg)

If Not (CBool(OrderLineObject.nGetValue("TaxAmt", taxam))) Then MsgBox(OrderLineObject.sLastErrorMsg)
If Not (CBool( OrderLineObject.nGetValue("QuantityOrdered", qua))) Then MsgBox(OrderLineObject.sLastErrorMsg)
If Not (CBool(OrderLineObject.nGetValue("UnitPrice", unitprice ))) Then MsgBox(OrderLineObject.sLastErrorMsg)
If Not (CBool(OrderLineObject.nGetValue("ExtensionAmt", Totalprice ))) Then MsgBox(OrderLineObject.sLastErrorMsg)
If Not (CBool(OrderLineObject.nGetValue("QuantityOrdered", qua))) Then MsgBox(OrderLineObject.sLastErrorMsg)

Note that you are just reading the data so you don't need to SetKeyValue, just do a GetValue on all fields.

Thx BigLouie

its working but i am not able to loop through the line, can you please help me on how can i loop through lines ?

Kinda busy right now. Seach in the Business Objects section for examples on how to loop through the lines.
