Hi Monika
First of all your code should look similar to the below except mine is a AP credit note based on a AP invoice, so you should change it for purchase order where i have invoice, and AP invoice where i have credit note. Also remember the "baseentry" number is not the docnum. It is the DOCENTRY of the document you want to base it on which in your case is the purchase order. You need to look in the database for the docentry in Purchase order header table. If you only have one series then it will be the same as docnum but if you have multiple document series for that document it will be different.
    Private Sub PurchaseCreditBasedOnPurchaseInvoice()
        Dim oCredit As SAPbobsCOM.Documents
        oCredit = oCompany.GetBusinessObject(SAPbobsCOM.BoObjectTypes.oPurchaseCreditNotes)
        oCredit.CardCode = "ADA001-S"
        oCredit.Lines.BaseType = SAPbobsCOM.BoObjectTypes.oPurchaseInvoices
        oCredit.Lines.BaseEntry = 1055
        oCredit.Lines.BaseLine = 0
        If oCredit.Add() <> 0 Then
            oCompany.GetLastError(lRetCode, sErrMsg)
            MsgBox(sErrMsg)
        End If
    End Sub
Hope this helps
