Hi Gurus,
   Can any one explain me.the best method of importing bew columns in the existing FM model.
   I have imported all the table into FM and design phase is completed and started working on the reports now there was an addition  of new column in the database and i need to bring into the FM and use in reporting.
  I want to know which is the best method that will reduce the burden of the whole model in importing.

Thanks in advance,
