Infinite Loop in Report Interconnect

I have a UBE and it calls itself Synchronous.   In the report interconnect data structure, I have a variable called cCallSelf_EV01 and when it calls itself, I set it to N.  In the After Last Object Printed of the main driver section, I put in the code saying if cCallSelf_EV01 is not equal to "N" then call itself.

So the first time it runs, the cCallSelf_EV01 should be null so it will call itself.  But it should stop the 2nd time since I set this variable to "N"

I tried using Processing Option but still the same result.  It's stuck in an infinite loop and it keeps calling itself.
