Field Symbol

[Former Member]

Hi !

I want to do a dynamic assignment for a variable. I want to assign to variable L_AUX1 a value, but the output is empty.

Any ideas?

REPORT  Z_output.

  data: L_AUX1(50),
        L_AUX2(50).
  FIELD-SYMBOLS: <fs1>.

  L_AUX2 = 'L_AUX1'.

  assign (L_AUX2) to <fs1>.
  write :/ sy-subrc.

  assign 'TESTTTTT' to <fs1>.
  write :/ sy-subrc.

  write :/ 'FS:  ',<fs1>.
  write :/ 'AU1: ',L_AUX1.
  write :/ 'AU2: ',L_AUX2.

The output is as follows:

0

0

FS: TESTTTTT

AU1:

AU2: L_AUX1

I want L_AUX1 to have the value ' TESTTTTT' (obviously in a dynamic way!) Why is it empty ?

If you are trying to assign a value to L_AUX1, then change your code like this.

report  z_output.

data: l_aux1(50),
      l_aux2(50).
field-symbols: <fs1>.

l_aux2 = 'L_AUX1'.

assign (l_aux2) to <fs1>.
write :/ sy-subrc.

 <fs1> = 'TESTTTTT'.      "<---- RIGHT HERE
write :/ sy-subrc.

write :/ 'FS:  ',<fs1>.
write :/ 'AU1: ',l_aux1.
write :/ 'AU2: ',l_aux2.

B/c you declared it in a DATA statement... but then never assigned any value to it.

Hi,

You have declared the variable L_AUX1 but not assigned any value. hence it is empty.

try the below code.

L_AUX1 = 'testing'.

assign (L_AUX1) to <fs1>.

write 😕 'Value in variable L_AUX1 is ', <fs1>.

thanks,

Just change your second ASSIGN statement to a simple = as below.

Change this

assign 'TESTTTTT' to <fs1>.

To this

<fs1> = 'TESTTTTT'.

Look what your code is actually doing:

1 - You give L_AUX2 the value 'L_AUX1' .

2- Then you assign the Field Symbol and write the return code 0.

It is correct because the return code 0 means that it was correctly assigned.

3- Then you assign 'TESTTTTT' to <fs1>.

<fs1> receives the value 'TESTTTTT' and again you write the return error code ( 0 ) wich is correct.

4- Then you wirte <FS1> hat has the value TESTTTTT.

5- Write L_AUX1 that has no value.

6- write L_AUX2 that has the value 'L_AUX1'.

Any question?

Reward with points if helpul.
