Hello Satish,
I have been following this thread for a while and had to re-read it a couple of times in order to understand what was the initial issue, the fixes applied, solutions discarded, etc...
In your message you posted Jan 26, 2015 11:28 PM, you said "I managed to remove the error message by adding partner group PGLDT2 where necessary but the order continues to be on block".
So I guess that means you managed to get rid of the message "License is required for country US SG IN (see log)" but you are still facing the issue that your document is still blocked. Correct ?
If the message has disappeared, then 50% of your issue is solved. Correct ? 
I don't know if the document is still blocked due to the original issue (that you solved by adding partner group PGLDT2) or due to another reason.
Do you mind sharing a screen shot of the compliance log you are now having for your blocked document ?
As well, does the document show up in the blocked documents report or you think it is blocked because you have a red traffic-light in the compliance log ?
Regards.
