How to use "Branch" operator?

Hello, everyone.

I want to use "Branch" operator properly.


For example, if my example set has an attribute called "sales"

and if sales >= 1000, then go to proceed to the subroutine A

and if sales < 1000, then go to proceed to the subroutine B

using "Branch" operator (then part - subroutine A, else part - subroutine B)

How can I do that?

I don't know how to how to fill in "condition type", "condition value" of "Branch" operator


Thanks in advance

    Hi,

    Do you have only one row in your data used as input to the branch?  In this case, you can use the attribute_value_filter and write something like Sales>1000 into the condition values.  The first process below shows an example for this.

    Or do you have multiple rows and would like to do one thing to the rows where the condition is met and something else where it is not?  In this case, you can simply use the operator Filter Examples and use the first output port for the cases where the conditioned is matched and the third port (called "unmatched") for the cases where the condition is not matched.  This is Example 2 below.

    Hope this helps,
    Ingo
