Hi Sudhir,

What you need is an accumulate. I recommend you to read documentation about
it.
I've attached a test case of your scenario.

Best,

Hi All,


I have a scenario which is similar to the one detailed below

There is a class Student and each students has a list of subjects.
Each subject has a name and a flag which is an indicator of pass or
failure.

Now how can I write a rule which tells me if there are atleast 10
students who failed in a subject maths.

Thanks
sudhir.
