Hi Kalyani,

Structures are created in Data dictionary and are persistent. whereas internal table are confined to a program and exist till the execution of the program.

HI,

You will use structure if you have to hold data of only one row. if data is more than one row than you have to use internal table.

Structure can also be used to hold the data of internal table header data. as object oriented does not support internal tables with header line.

*this is internal table.

DATA: itab like standard table of tab.

*this we can say structure or work area.

data: itab_wa like line of itab.

Regards,

Structure can also containmemory space.

Structure is used to have a single record, internal table is for no. of records.

Structure is also used to define an internal table using 'DATA' statement.

whenever you want to store the data then you have to use internal table

when you want to define the internal table with any particular fields then use structures and use table type structure
