Hi experts,

What is the difference between the following 2 syntax:

data: lt_vbak like table of vbak.

data: ls_vbak like vbak.

I will reward all the helpful answers.

Hi Ajay,

data: lt_vbak like table of vbak.

Means defining one internal table lt_vabk with structure of VBAK which has been defined in the Dictionary.

data: ls_vbak like vbak.

Means defining one structure or work area with structure of VBAK which has been defined in the Dictionary. I hope that it helps u. Regards, Venkat.O

Hello Venkat,

From your reply it seems that the following 2 syntax:

data: ls_vbak like vbak.

&

data: ls_vbak like line of vbak.

are same?

Is it true?

Thanks,

Ajay.

[venkat_o]

No Ajay. Both syntax are not same. You have to write like below.

DATA: ls1_vbak LIKE vbak.

DATA: lt_vbak LIKE TABLE OF vbak.
DATA: ls2_vbak LIKE LINE OF lt_vbak.

Above statements syntax correct. But ls1_vbak and ls2_vbak structures are same. Regards, Venkat.O

Hi ,

data: lt_vbak like table of vbak.

This will create an internal table without header line.

data: ls_vbak like vbak.

This will create only work area or structure.

Hi ajay,

the first statement

data: lt_vbak like table of vbak.

declares a table lt_vbak having the same structure as vbak

the second statement

data: ls_vbak like vbak.

will not create a table,instead it will create a work area/headerline (a table line) having the same structure of vbak

Dear Ajay,

The first statement creates an internal table without header line where every row is of same type as VBAK.

The second statement creates a structured variable which has the same type as VBAK.

Internal table is a variable in ABAP program and denotes an array where each element has the same type and structure as VBAK.

(VBAK is a database table and referring to VBAK in ABAP only refers to the structure of VBAK's one row, not the array/ complete table in the database)
