Hi Surya,
Very valid questions asked and I feel disappointed that despite 4 yrs, I still stand at same place where you were in 2010. I also have the exact questions as I could not find any proper document related to IS transports. There many ifs and buts and dos and don't and with my experience in SAP CRM, I generally prefer to find the right ways and learn from the lessons others might have learnt when trying the same thing.
Can you please advice from your experience your take on the approach and procedure for IS transports for these questions ?
Thank you so much in advance.
Best Regards
Suchita
