Hi Sushant,
ChaRM has many sub features like CSOL where
ChaRM controls the entire Change Management process for you but CSOL is just creating lock and avoiding conficts.
It seems what your requirement is to have change management in place without TMS connection right?
you can use that .....we have control status switches in ChaRM Project where you can control the release or import of changes via erp dev etc directly
But why you don't want to use this good feature of ChaRM where you can automate the above work
hope this helps
Regards
Prakhar
