Need to determine if request set running and parameters

[wrwelden]

I can query table FND_CONCURRENT_REQUESTS to determine if a certain request step is running.

select description, status_code, number_of_arguments, argument1, argument2, argument3, argument4
from FND_CONCURRENT_REQUESTS
where description =  'XYZ_YEAR_END_GL_VERIFY (30)' 
 and status_code != 'C'

but the columns like 'argument#" do not seem to coorespond to concurrent request parameter values.

I need to be able to determine if a certain concurrent request is running and the value of certain input parameters (ORG_ID, SOB_ID), in my case the parameter I am interested in is the first one defined under "Program", "Define", then query executable, then select "Parameters".

I want to programatically prevent this procedure from running with the same input criteria simultaneously.

Has anyone done this? Help!
