Chaining rules, including those in decision tables, can be achieved by using a transient control fact.<br><br>rule "your DRL rule 1"<br> when<br> YourObject( field == 1 )<br> then<br> insertLogical( new TransientControlFact( "dtable1" );<br>
end<br><br>rule "your DRL rule 2"<br>
when<br>
YourObject( field == 2 )<br>
then<br>
insertLogical( new TransientControlFact( "dtable2" );<br>
end<br>
<br>Then in the decision table use the transient control fact in an additional column. The DRL would look like this:-<br><br>rule "dtable1 row 1"<br> when<br> TransientControlFact( dtable = "dtable1" )<br>
YourOtherFacts( )<br> then<br> ....<br>end<br><br>rule "dtable1 row 2"<br>
when<br>
TransientControlFact( dtable = "dtable2" )<br>
YourOtherFacts( )<br>
then<br>
....<br>
end<br>
<br>How you retrieve the results from the Decision Tables is up to you (e.g. queries, globals etc).<br><br>With kind regards,<br><br>Mike<br><br><div class="gmail_quote">On 10 October 2012 09:34, Manasi <span dir="ltr"><<a href="mailto:manasi.a.damle@capgemini.com" target="_blank">manasi.a.damle@capgemini.com</a>></span> wrote:<br>

<br>
With Drools I need to execute a DRL first and based on its output value I<br>
need to evaluate a decision table in guvnor and get the output values.<br>
<br>
Please let me know how this can be done.<br>
<br>
Thanks,<br>
