Hello Balu

In order to display some tabular data in an ALV, the ALV needs some information about the columns/ fields which will be displayed in the ALV. Field catalog is basically the internal table which carries information about each of the columns/ fields with which ALV has to deal with. It need not necessarily contain information about each of the columns/ fields in the data table used as data source of ALV. Only the fields which are important for display or of some technical use for ALV need to be informed to ALV through field catalog.

You can get some more details by following the link:
