hi there...

Structures basically are a design of the table which get filled only on run time.

In report program, structures can be used to define an internal table. the syntax is

Data : itab like str occurs 10 with header line.

where str is the structure.

u can compare the structure with a header line or a work area which also gets filled on run time.

otherwise, there is no other use or significance or structure.

Do reward if helpful or get back if further clarification is required.

Hi ,

Structures are created in DD.So the DD objects are globally avaliable to all the work bench tools.

We use the Structures in programs to crete the data objects like field strings

example:

if we have a structure ZSTRUCT in DD.

in prog

data fs_data type ZSTRUCT.

We use the structures in programs to create intenal tables.

data itab_data type standard table of ZSTRUCT.

The main advantage of creating structure in DD is if there are any changes are done on structure those are reflect on all programs using this structure.
