Difference between internal table definitions

[Former Member]

What is the difference between the following table definition syntax?

(Def 1: Data: g_t_vbak type table of Vbak occurs 0.

Def 2: Data: begin of g_t_vbak occurs 0,

<Field1> type <Data type>,

…

End of g_t_vbak.)

a. Both are same

b. Def 1 and Def 2 create an internal with header line.

c. Def 1 creates an internal table without header line but Def 2 creates internal table with header line.

d. Def 1 creates an internal table with header line but Def 2 creates internal table without header line.

if possible explain

Def2 : U can declare your own fields for the internal table ..

Hi,

A is the answer

Data: g_t_vbak type table of Vbak occurs 0.

Here, OCCURS statement is used to declare a structure as an internal table. The initial size of internal table ranges from 0 to 7.

Data: begin of g_t_vbak occurs 0,

<Field1> type <Data type>,

…

End of g_t_vbak.)

Any internal table created using BEGIN OF - END OF statements is called as structured internal table.

if it has Begin,then it is with header line – Creates work Area

Occurs n – Creates the body of the internal table

Hope this helps u,

Hi Type table of VBAK creates internal table with same structure like VBAK.

Begin of itab creates internal table with ur own fields.

In this u can define as many fields u want and with any type.
