Hi Swee,
Basically in my First queue i am having 5 entries with key123 as one of the field and in second queue i might have 5 entries with Key123 or some times it might not be 5 it might be existing or not also.
I need to pass 2nd queue entry to only for the first queue entry where this key matches if not i need to pass Empty context.
Remember second queue might exist or not also and both queue 1, queue2 are in same level.
Hope this clarifies.
i was thinking based on my example provide if Queue1 has value X then pass [] else pass the first value of Queue 2 to the first non exisiting value X.
Correspondingly 2nd non X value should be replaced with 2nd value of QUEQE2.
Thanks,
Ch
