variable reference

Former Member — Fri, 17 Mar 2006 05:10:33 GMT

I Have to refer a variable using another variable..

Using that variable i have to set the value to that refered variable..

for example

I have a variable called matnr01 to matnr12..

I Have to refer the variable like

field1 = 'matnr01'.

If iam setting the value to the field1..it should set the value to matnr01..(like pointer concept in c)

Is it Possible in ABAP?

Pls reply immediately.

Try using the code below:

DATA: matnr01 like mara-matnr,

matnr02 like mara-matnr,

matnr03 like mara-matnr,

matnr04 like mara-matnr.

field-symbols <F1> type mara-matnr.

Assign matnr01 to <F1>.

<F1> = '100'.

Assign matnr02 to <F1>.

<F1> = '200'.

Assign matnr03 to <F1>.

<F1> = '300'.

Assign matnr04 to <F1>.

<F1> = '400'.

Write : matnr01, matnr02, matnr03, matnr04.

Hope this helps.

Hi Abijith,

Thanks for the reply..

Move '100' to (var_name) shows me a error in that line.

It's not working..

Is there any other way...

Thanks..

Hi Priya,

I think you are talking about field symbols in ABAP.

Just see the definition of a field symbol:

Field symbols are placeholders or symbolic names for other fields. They do not physically reserve space for a field, but point to its contents. A field symbol cam point to any data object.Whenever you address a field symbol in a program, you are addressing the field that is assigned to the field symbol

syntax for field symbol is

FIELD-SYMBOLS <Fieldsymbolname> TYPE type_name.

eg: FIELD-SYMBOLS <FS> TYPE I.

You can assign a field symbol to any field using ASSIGN statement.

Let me give u an example of how to convert ASCII to char using field-symbols

data : c.

field-symbols : <n> type x.

data : rn type i.

c = 'A'.

assign c to <n> casting.

move <n> to rn.

write rn.

Output: the ascii value of 'A' is displayed.

I hope u got some idea.

Regards,

Sylendra.

Hi,

The same thing can be put into a loop as below.

DATA: matnr01 like mara-matnr,

matnr02 like mara-matnr,

matnr03 like mara-matnr,

matnr04 like mara-matnr.

field-symbols <F1> type mara-matnr.

data: varname(7) type c.

data: indx type n.

do 4 times.

indx = sy-index.

concatenate 'matnr0' indx into varname.

Assign (varname) to <F1>.

<F1> = indx.

enddo.

Hi priya,

1. Very simple.

2. We have to use FIELD-SYMBOLS

and another variable for FIELD NAME.

3. just copy paste in new program

(there will be a selection screen,

there u just enter

MATNR01

MATNR02

MATNR03 OR

MATNR04

It will give the value in that variable.

REPORT abc.

PARAMETERS : fldname(30) TYPE c default 'MATNR01'.

*----

DATA : matnr01 LIKE mara-matnr,

matnr02 LIKE mara-matnr,

matnr03 LIKE mara-matnr,

matnr04 LIKE mara-matnr.

FIELD-SYMBOLS : <f> TYPE ANY.

*----

matnr01 = 'Mat 01'.

matnr02 = 'Mat 02'.

matnr03 = 'Mat 03'.

matnr04 = 'Mat 04'.

*----

ASSIGN (fldname) TO <f>.

WRITE 😕 <f>.

regards,

amit m.
