Hi
I have an interface with load and with, when a user updates a value in the interface I need to return a boolean value and I am using that in another rule.
In the load I have a local variable in which I am saving the old value and in the with I an doing a isnull(symetricdifference9oldval,newVal) and assigning this to a local variable and passing this to the other rule.
I am having an issue in setting the boolean value please advice me here.
Thank you.

Hi,
From your question, I could understand that you're assigning the result to a variable in load() again, This will not work as load variables will be executed only once. If that's not the case, please share your code here(by using insert->code) for better understanding.
Alternatively, if your Appian version supports a!localVariables(), then it'll be a lot easier to implement.
Hi Selvakumar,
I am assigning the local variable with the result in the with and using the result in the with to pass to a child interface.
I have a form layout in the with and I am declaring everything before the form layout. I hope the below code snippet helps to guide me. thank you.
load( local!oldVal: employeeData_cdt.empName, ) with( local!isReadOnly: if( and( isnull(symetricdifference(oldval,newVal) ) ) ) a!formlayout( rule!EMP_Details( /*this is the child interface where we can edit the empl details and if the details are modified I need to update the local!ReadOnly to true or false. ) rule!EMP_Validatedetials( local!isReadOnly, ) ) )
Appian is a functional language. This means that you need to nest your function call.
E.g. for load(): The first "lines" are used to define local variables created in the scope of that load() call.
