Even I heard that we can use the data page but where actually in the data page rule form we refer to different threads? Since the scope is requester, will it be applicable to all the threads with in the requester scope?
And if the above discussion is true how actually do we refer and map the value of that particular parameter value?
In one of our legacy projects we used custom function and felt declare/data page with a proper logic would be easy to maintain shared data instead of custom function. but again, we are still using custom function only.
