what is table type and line type and how both are related

Hi

As the name suggests, line type will create data for storing only one record or like structure and table type is for creating a table for the structure mentioned.

Usually when you create a table, you add all the fields you need.

A table type is based on a structure. Instead of adding fields, you just add one structure. Very useful sometimes. Especially in OO.

The transaction is just SE11. When you select create, you can choose 'Table type'. Then you enter a structure in the row type.

If you are declaring any STRUCTURE on your program, then we can represent those as

TYPE linetype

.

This would make the data declaration more understandable.

HI,

line type will act as a structure(wa).we can store only one reocrd.

table table will act as an internal table without header line.

Hi,

Table type is used to declare an internal table.

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

Example:

data: begin of ty_mara,
        matnr like mara-matnr,
        werks like marc-werks,
        maktx like makt-maktx,
end of ty_mara.

Data: it_mara type table of ty_mara.

Data: wa_mara like line of it_mara.

Here you are creating an internal table it_mara of type ty_mara. For work area you are creating a structure wa_mara which looks like a line of it_mara with same fields.

HI

A table type describes the structure and functional attributes of an internal table in ABAP. In ABAP programs you can reference a table type TTYP defined in the ABAP Dictionary with the command DATA

A table type is a type that describes the structure and functions of an

internal table in the ABAP program.

It describes the following attributes of an internal table:

1- Row type,

2- Key definition,

3- Key category,

4- Access Mode.

It is also very useful in defining internal tables, that need to be exported to the Smartforms in the form Interface.
