How to assign number of examples as a macro value in create example set operator.

So, I have a problem statement in which total examples for create example set operators are variable and I am trying to assign them through a macro input. However, I believe the create example set operator does not take marcos as input. Please see the below snapshot of the process.

    Hello @hbajpai

    I tried using set macro with a value of 100 and macro name as "name". Then I used create exampleset where I called that macro %{name} in the number of examples and it worked. Can you check your macro is returning a value (number)? You can check this by enabling macro window in View --> Show Panel --> Macros. Try to set a breakpoint before create exampleset by right-clicking on it and run it to check macro value.

    @varunm1 In the standalone cases, I have tried too and it works as you demonstrated in the above example. In my situation, the macro is returning a number, I even used eval() to ensure it.ย  I have attached the XML code of the mock process to demonstrate the error.ย
