Thanks for your reply.
Any guess on not getting emails?
I have used same process by refering link Mail without email adapter? Part - I - Process Integration - SCN Wiki
but email is not triggering, I have hard coded values in UDF, I used correct mail server from SCOT... no clue where i am going wrong.
Regarding maintain order in run time, i am working on that and stuck with other question, do you know how to search for string "ABC" in source value. Because source value contains unlimited number of strings, i need to search for "ABC" value from that. i can't use sub string function because i don't know where exactly i get "ABC" in source value.
I used contains("ABC") equals "true" in receiver determination but it is not working. Please suggest.
