Hello,
I have two macro
%{key} and %{value}
Product and Credit Card,Travel Card
I want output

@sgnarkhede2016 splitting of macros will majorly depend on how you will use the macros in the process. I created a mock process that uses comma to separate value into macros. It is not super elegant but does the job.
