List list = new ArrayList(); CashMemoHdr hdr = new CashMemoHdr(); hdr.setLineItems(2l); List<CashMemoDtl> cashMemoDtls = new ArrayList<CashMemoDtl>(); CashMemoDtl dtl = new CashMemoDtl(); dtl.setArticleCode("BabySoap1"); dtl.setLineItemNumber(1); dtl.setPrice(250L); dtl.setLineDiscount(5L); dtl.setQuantity(5l); cashMemoDtls.add(dtl); list.add(dtl); dtl = new CashMemoDtl(); dtl.setArticleCode("BabySoap2"); dtl.setLineItemNumber(2); dtl.setPrice(40L); dtl.setLineDiscount(3L); dtl.setQuantity(5l); cashMemoDtls.add(dtl); list.add(dtl); dtl = new CashMemoDtl(); dtl.setArticleCode("BabySoap3"); dtl.setLineItemNumber(3); dtl.setPrice(30L); dtl.setLineDiscount(2L); dtl.setQuantity(2l); cashMemoDtls.add(dtl); list.add(dtl); hdr.setCashMemoDtls(list); rule "Buy BabySoap2 & Get BabySoap3 Free" when :CashMemoHdr(lineItems:lineItems,totalItems:totalItems,costAmt:costAmt ,cashMemoDtls:cashMemoDtls) :CashMemoDtl(articleCode:articleCode,lineItemNumber:lineItemNumber,price:price, netAmount:netAmount,lineDiscount:lineDiscount,quantity:quantity, promotionId:promotionId) //> eval($c.getArticleCode()== "BabySoap2") then +$c.getArticleCode()); end pls give me proper idea about of this.
