[PAYET, Manuel]

By the "solutions given" I didn't mean to tell mine was good, apparently it's not, I was talking about the other ones.

This will not work.  Rules will not predictably react to changes in global variables.  Use an object in working memory.

If I were you, I'd use something like 

Global java.lang.Integer cnt;

Rule "before everything"
Salience 10
When
Eval(true)
Then
Cnt=0
End


Rule "condition A"
When
condition A
Then
 cnt=cnt+1;
End

Rule "condition B"
When
condition B
Then
 cnt=cnt+1;
End

Rule "condition C"
When
condition B
Then
 cnt=cnt+1;
End


Rule "action 1, after everything"
Salience -10
When 
   eval(cnt>=2)
Then
   execute action 1
End


Of course, if you change the fact, you'll probably have to think about things like lock-on-active to increment only one time the cnt variable

Hello,

we are using Drools in our company. We have a rule with three conditions in this format:

when
    Condition A
    Condition B
    Condition C
then 
    execute Action 1

Now we have a situation, in which the rule should fire if AT LEAST two of the three conditions are satisfied. Do you know how to implement this? Any ideas or hints?

Many thanks and regards!

skasab2s.
