Hi Vikram,
I checked the points you mentioned.. product investigation is assigned, there are the correct service and response profile too. But the calculated dates are wrong, e.g.
message created at WE 30.04.2014 13:53
calculated IRT FR 02.05.2014 11:53 << should be WE 30.04.2014 14:53
calculated MPT MO 05.05.2014 09:53 << should be WE 30.04.2014 17:53
see screenshot
Don't know what to check further..
Regards, Richard
