how long will the field value will retain?

Hi,
I have field (say MN_APPLICANTID), I made it as the url parameter, when the form is accessed it received the value, and then the flow go to function and then back it again.
My question is, why the value of MN_APPLICANTID is become null after go to the function? the function is just doing a fetch, check if the fetch result is null or not and back to the caller.

A field value is only changed when something specific changes it. From your description, most likely is that you have it mapped to the database resource that you are issuing fetch against and it is fetching a null value.

IC.
Yes, exactly that's what the function do. But the result is not null.
But at least now I know which part that change the value of the field.
Thank you.
