Thank you for the reply Kanap, but I am trying to create a function that will have the values act as parameters because another case will not have the same numbers. Please guide me how to accomplish this.
I see that this is regarding the response you are receiving from Service. In the response Data Transform, after the properties are mapped, you can use declare expression to calculate the percentage using the divide function as mentioned above.
Could you please check the clipboard structure of connectRest.response_POST.results_Summary.tests and define each page connectRest,response_POST.,esults_Summary.,tests in pages and classes with resepective class.
And one more thing, I think the above page is related to Response you received from REST integration and you can handle the mapping in the response Data Transform itself, instead of having a new Data Transform.
