Eli Sir
Thanks for replying. Yes sir you are right that it is not mandatory in any rules to maintain year dependent Number ranges for CO documents, I have also observed that with every restart of application server some numbers are skipped. But my point of Argument (sorry i can not argue with you) asking is that if some body wants to maintain it as year dependent for better identification what could be harm in it. Sorry if it irritates you but please try to think on the above line.
High Regards
