I will try what is written there

Your predicate expression has local variables. Update these similar to that example.

Hi Richard,

I am doing Shpitzer clearing schedule.

For that I need to use values from previous iterations.

To my understanding the only way to get results from previous iteration is with reduce.

It works by the way - I just wasnt able to use local variables which made me repeat calculations...

Thanks,

Thanks Stefan!

Can you give an example? just how to declare the a!refreshVariable in the right context ?

Thanks

That's pretty simple. a!localVariables does not re-evaluate local variables by default when used inside reduce(). To make this work, you need to declare the value of the local using a!refreshVariable and set refreshAlways to true.

the information is pretty limited. can you tell as about your overall use case?
perhaps reduce() is not the right fit :)
