            custInvoiceLine.initValue();

            

            //setup main account as required 

            offsetDimensions = ["3434","3434", 0, "", ""]; // you can set a Main Account with multiple financial dimensions

            custInvoiceLine.LedgerDimension = AxdDimensionUtil::getLedgerAccountId(offsetDimensions);

            custInvoiceLine.initFromCustInvoiceTable(custInvoiceTable);

            custInvoiceLine.ItemId = "erw234324"; //custom field     

           

            custInvoiceLine.Quantity = custinvoicetrans.Qty;

            custInvoiceLine.UnitPrice = 1210 ;

            custInvoiceLine.modifiedField(fieldNum(CustInvoiceLine, UnitPrice));

            custInvoiceLine.Description = custinvoicetrans.itemName();

           

           

            custInvoiceLine.ParentRecId = custInvoiceTable.RecId;

            if(!lineNum)

            {

                lineNum = CustInvoiceLine::lastLineNum_W(custInvoiceLine.ParentRecId);

            }

            lineNum += 1;

            custInvoiceLine.LineNum = lineNum;

            custInvoiceLine.InvoiceTxt = custinvoicetrans.InvoiceId+"\n"+date2StrXpp(custinvoicetrans.InvoiceDate);//change it as per need

            custInvoiceLine.insert();
