hi , 
  I am able to fire the rules in drools...But i want to fire the rules after modification of same data 
ie.., i want to fire the rules twice in the same session 

for example:  i have some stock of different items, if the particular stock item quantity is less than minimum quantity i want fire a rule that order that quantity 

after that the stock is added to that previous count(stock), i want to recheck the stock positions and again need to fire rules 

is it possible to fire the rules twice or more in Drools 

if, please provide me some sample code.... 
  
I want to know that Drools can fire a rule multiple times in one session or not???? 
      
please let me know if possible and guide me in this scenario 


thanks in advance
