Hi Pankaj,
BBPV_PTERM_LOCAL is table joint of BBP_PAYTERM_TEXT and BBP_PAYTERM transparent tables.
If you maintain using BBPV_PTERM_LOCAL it updates both these table with logical system whichever you have defined as LOCAL in the customization "Define System Landscape".
If you want to replicate from other system you use BBP_UPLOAD_PAYMENT_TERMS. Here you enter the back end logical system name which you need.
My suggestion of BDC recording for SM30 is a generic one. You can use it for any maintenance view table.
If you want to make your own maintenance view for a standard table blog by Konstantin Anikeev as per link http://scn.sap.com/community/srm/blog/2014/06/19/create-a-maintenance-view-for-sap-standard-table should help you.
