Queries on Vendor Name - LFA1-Name1 Vs ADRC-Name1

Hello

I have few queries.

1. How do i make sure to display Vendor Name picked up from ADRC table ( 40 characters) in Standard SAP Reports and Print programs? Is there a SAP Note that can help with that? in Current scenario the screen display is of 35 characters and also standard SAP report displays 35 characters.
2. Is there a Standard object / BAPI or function module that will load Vendor Name of 40 characters from an input file?
3. Can someone suggest a step by step approach to move from Vendor Name currently pick up from LFA1-Name1 to ADRC-Name1 in Purchase orders, requesitions, reports, layouts etc?

Many thanks

Manu
