Thanks Anita,
Will go through the note and will revert back, incase of any further issues.
Also, I want to know why I am not able to delete a project, and when trying to delete a project, that doesn't have a package in it, gives an error. something that says, 500 sap internal error, screen output without connection to user ( termination : RABAX_STATE)
Also, based on my earlier msg, I was trying to go through the tcode " SET_RFC_STATE".
Surprisingly, I see all the Projects that I created with the earlier source/target/RFC connections.
Is there a way to get rid of these projects/ packages which are not in USE.
Thanks,
