HI Saurabh,
Just be careful making the setting where you did as this is in the standard SAP delivery config and may be affected when you do upgrades in future. The node I specified is where you really should be doing your customising (and there are a few other examples like this throughout, e.g. the Global Settings provided vs. the override global settings options where changes should be made).
The system checks whether any custom changes have been made in these areas, and if no then reverts to the standard settings supplied. You have now updated the standard settings which is not ideal
Regards
C
