clarification regarding TYPES

[Former Member]

Hi all,

I need clarification regarding below code....

TYPES: BEGIN OF TY_TAB,

VBELN TYPE VBAK-VBELN,

ERDAT TYPE VBAK-ERDAT,

END OF TY_TAB.

TYPES: TAB TYPE TY_TAB OCCURS 1.

From the above code What exactly TAB means whether it is an internal table with header line or else only work area or else is it a structure?

Thanks & Regards.

TYPES: BEGIN OF TY_TAB,

VBELN TYPE VBAK-VBELN,

ERDAT TYPE VBAK-ERDAT,

END OF TY_TAB.

TYPES: TAB TYPE TY_TAB OCCURS 1.

all the above statements are TYPES. The first one is the TYPES definitation for a structure. The second is a table type definitition.

Only WHEN YOU USE DATA statement the memory is allocated.

so you need to have

DATA: IT_TAB TYPE TAB.

ONLY When you have a data statement the definitaiton is complete.

Hi VJ,

Table type definition means that TAB comes under structure or internal table?

Its a table. Coz they have used OCCURS 0 in the types.

It is just another TYPE.. An itab/wa/structure has to be declared with the keyword DATA referencing a TYPE.

Hi laxman

The type that you declare is type of internal table. you can create internal table by reference this type.

Example

Data it_tab type ty_tab.

it_tab is internal table , not a structure.
