HI Guys,
Sorry I was busy in other issue due to which I could not update the solution and as you have mentioned in your thread that was the solution for request download.
In case of Initial download I set the indicator for "Display Leading Zeros" in the IMG customizing and the steps to navigate is as follows,
IMG-->CRM-->Cross Application Components-->SAP Products-->Data for Converting the Product ID
Thanking all of you again.
Regards
