Hi Vandana,
The field that you are trying to modify is a standard table field. Hence you will need to get the Access key for changing the same.
The implications that Prabhu says that you need to take care of can be :
-Since you are changing a standard table field, it will affect all the places where this field is being used, when I say all the places it basically means Transactions, programs, views SAPScript. These might result in errors in programs and short Dumps in Varying Places, also it might affect the Function Modules that are using this field. To make the long story short a lot is at risk, and it would be very difficult to check for all the scenarios.
Regarding getting the Access Key, usually developers dont have change access to the Standard SAP Objects, to make change to Standard SAP Objects you need to get an Access key from the SAP Team. Maybe any of your senior will be able to tell you about the Access Keys.
As far as possible dont go for changes to standard SAP Objects, because usually SAP would not take responsibility for issues arising due to change by developer by using an Access Key.
Hope it lays to rests all your queries. Alternative solution can be thought of once you tell why is it that you want to change the field length.
