Hallo All,

I have two excel files one is Main_data.xls and second one is
Secondary_data.xls having some of the columns from Main_data.xls

when every I add or change some data in Main_data.xls it should also change
in Secondary_data.xls file.

I have different columns in Main_data.xls in columns A, C, E when ever there
is a change in data it should also be updated in the columns A, B, C of
Secondary.xls file.

kindly help me regarding this.
