hi,

internal table store data temporarily . Work area is just work as a header for that IT table .That mean if we r filling IT table first work area will fill by that data then data will transfer to body of IT table.

when we use IT table for some operation ( Insertion or Deletion) first its WA will fill by one record then operation will perform on IT table.

Body- is the part of It table where whole data of IT table store temporarily.

There r different type to declare a IT table or WA as-

data : begin of it occurs n ,

a1 type c,

a2 type c,

end of it.

this will create IT table with WA & body, if we do not maintain with occurs it will create only body of IT table.

data it1 type table of DDIC with header line.

this will create IT table with WA & body, if we do not maintain with header line it will create only body of IT table.
