Hi prashanth,

1. is HIDE area is a table?

Not is not a table.

It is just like a list (used with write statement)

the difference is, its not writen on screen,

instead it is STORED in memoery. (Line by line)

Just as we use write, we use

HIDE variablename.

and the value of the variable is STORED in memory

on the particular line number.

(we can retrive its value , on that particular

line number, when we doubl-click on the line

which is displayed using write)

2. for getting the taste of it ,

use this program (just copy paste)

(it will show u hidden fileds)

(it will display 2 lines, then on double-clicking,

it will show the hidden values 1000,2000)

REPORT abc.

DATA : a(10) TYPE c.

DATA : b(10) TYPE c.

a = '1000'.

b = 'mittal'.

WRITE : b.

HIDE a.

a = '2000'.

b = 'hello'.

WRITE 😕 b.

HIDE a.

AT LINE-SELECTION.

WRITE 😕 'hidden field a is : ' , a.

regards,

amit m.

Hi Prashanth,

it is not a table, it is just like a work area to hide the content of the write statement.

you can use after write statement of a variable, it will hold the value of the variable

Hi,

i am just giving the SAP help on Hide...

HIDE f. 



The syntax check performed in an ABAP Objects context is stricter than in other ABAP areas. See Cannot Use Constants in the HIDE Area. 

Effect 
The contents of f related to the current output line are stored. If this line is selected, f is filled automatically with the stored value. 



The selection can be made using: 

AT LINE-SELECTION 

AT PFx 

AT USER-COMMAND 

READ LINE 



You do not have to output the field with WRITE in order to be able to store its value. 



The HIDE statement does not support structures that contain tables (deep structures). 



System fields that are particularly useful in interactive reporting are listed in the system fields for lists documentation. 



Note 
You cannot save lines or components of lines of an internal table that is addressed using a field symbol to the HIDE area. (Compare the ASSIGNING addition to the READ and LOOP statements). Assign the contents of the line or component to a global variable and save this instead. 



Exceptions 
Non-Catchable Exceptions 



Cause: The field is too long for HIDE. 
Runtime Error: HIDE_FIELD_TOO_LARGE 

Cause: Cannot apply HIDE to a table line or component of a table line. 
Runtime Error: HIDE_ILLEGAL_ITAB_SYMBOL 

Cause: HIDE is not possible in a local field. 
Runtime Error: HIDE_NO_LOCAL: HIDE 

Cause: HIDE is not possible on an empty page. 
Runtime Error: HIDE_ON_EMPTY_PAGE

Hi prashanth,

1. Just type HIDE and press F1.

u will get the same help.

2. Now a days, HIDE concept

is not used much, bcos alv concept is there!

3. WHY HIDE IS Used :

BCOS To TRAP/DETECT USER-INTERACTION (DOUBL-CLICK)

a) Suppose a simple report displays

a basic list showing

vendor number, vendor name.

b) User-Double clicks a vendor

c) Then we want to show the details of this vendor

4. So , to DETECT, which VENDOR is CLICKED,

we can either use HIDE or

use system variable sy-lisel

which has the contents of the line

which is double clicked.

(in this case we have to PARSE/SUBSTRing

the whole line to split the vendor number)
