Never duplicate any derived information while the data object holding the duplicate is still in the system.<br><br>Given an invoice, you may associate its positions with a "tariff id", which lets you recalculate an (old) order repeatedly, guaranteeing stable pricing.<br>
<br>Only when this data is removed from the system you actually calculate and use the currency values.<br><br>-W<br><br><br><br><div class="gmail_quote">2011/4/17 Riyaz Saiyed <span dir="ltr"><<a href="mailto:riyaz.saiyed@emirates.com">riyaz.saiyed@emirates.com</a>></span><br>

<p class="MsoNormal" style=""><font face="Courier New" size="2"><span style="font-size: 10pt; font-family: "Courier New";">I'm doing a POC on drools
decision table. We need to develope pricing engine for few of our products. I
created xls with list of products and their price as per drools format. When I
load xls and run the rules, the price were picked up correctly against mathing
product, customer and quantity criteria.</span></font></p>
<p class="MsoNormal" style=""><font face="Courier New" size="2"><span style="font-size: 10pt; font-family: "Courier New";"> </span></font></p>
<p class="MsoNormal" style=""><font face="Courier New" size="2"><span style="font-size: 10pt; font-family: "Courier New";">Now I want to save the
executed rule so the if there is any modification in quantity
(increase/decrease), I can calculate the price again based on earlier executed
rule and not from xls.</span></font></p>
<p class="MsoNormal" style=""><font face="Courier New" size="2"><span style="font-size: 10pt; font-family: "Courier New";"> </span></font></p>
<p class="MsoNormal" style=""><font face="Courier New" size="2"><span style="font-size: 10pt; font-family: "Courier New";">I think to achieve the, I
need to store the "rule" against every order for each product. </span></font></p>
<p class="MsoNormal" style=""><font face="Courier New" size="2"><span style="font-size: 10pt; font-family: "Courier New";"> </span></font></p>
<p class="MsoNormal" style=""><font face="Courier New" size="2"><span style="font-size: 10pt; font-family: "Courier New";">Can any one suggest me, how
I can get the string representation of the executed rule so that I can create
.drl file from that string and run the same rule again for any order
modification.</span></font></p>
<p class="MsoNormal" style=""><font face="Courier New" size="2"><span style="font-size: 10pt; font-family: "Courier New";"> </span></font></p>
<p class="MsoNormal" style=""><font face="Courier New" size="2"><span style="font-size: 10pt; font-family: "Courier New";">I've looked at
SpreadsheetCompiler and was able to get the string of all the rules as a result
of compile method. </span></font></p>
<p class="MsoNormal" style=""><font face="Courier New" size="2"><span style="font-size: 10pt; font-family: "Courier New";"> </span></font></p>
<p class="MsoNormal" style=""><font face="Courier New" size="2"><span style="font-size: 10pt; font-family: "Courier New";">Note - I can not read xls
again for order modification because, if in between the price in xls has
changed, the engine should still pick the old price.</span></font></p>
