one real time use of both.

instead of line type we can directly use the corresponding tables.

Points assured.

line type refers to the structure of an internal table,whereas row type is the actual part that contains the data and it refers to the table body.creating internal table using line type and row type concept is for reusability purpose.Line type and Row type are defined at DDIC LEVEL. .

Line type is used to create work area for an internal table.

Ex:

data: begin of ty_mara,

matnr like mara-matnr,

werks like marc-werks,

maktx like makt-maktx,

end of ty_mara.

Data: g_t_mara type table of ty_mara.

data: wa_mara like line of g_t_mara.

here you are creating a table g_t_mara of type ty_mara. For work area you are creating a structure wa_mara which looks like a line of g_t_mara with same fields.

The line type of a table type can be defined by:

Specification of a type that already exists (data element, structure, table type, table, view) whose properties are then copied as properties of the defined table line.

Direct type input, where data type, number of positions, and, if required, decimal places, are entered directly.

Specification of a reference type.

structure

The table category defines how the logical table description defined in the ABAP Dictionary is represented in the database.

There are the following table categories:

transparent table

structure

append structure

For internal purposes, such as storing control data or update texts, there are in addition the following table categories:

pooled table

cluster table

generated view structure
