Hi Deepak,
It is nothing to be with the hedge plan, I am just trying to replicate exactly the same inputs that you provided in your system, in mine, in order to try to help you. Product Type 55A and 55C, have the same Product Type, Transaction Types and Flow types Configuration, and just with P.Type 55C, Tx.THMMM runs properly, so you must have some have something in your customizing settings that is not correctly set.
That is the reason that I am trying to replicate exactly the same of your deal, in order to,by trial and error, try to solve your issue.
Can you screenshoot your Exposure, Hedge Item and Hedging Relationship tabs of your PLAN002
Regards
Ignacio
