Problem while using Field-Symbols

Former Member — Wed, 13 Aug 2008 10:58:21 GMT

Dear Gurus,

I am using Field-Symbols in my report progm. Though I am assigning the table type to the declared field-symbol, my program is going to dump saying tht "GETWA_NOT_ASSIGNED".

My Code is as below:

FIELD-SYMBOLS: <f_itab1> TYPE vbak,

<f_itab2> TYPE vbap.

LOOP AT it_vbak ASSIGNING <f_itab1>.

READ TABLE it_vbap ASSIGNING <f_itab2>

WITH KEY vbeln = <f_itab1>-ww206.

ENDLOOP.

In debugging mode I see <f_itab1> is assigned but <f_itab2> is not being assigned and getting an error msg as "ERROR: Field symbol <f_itab1>is not yet assigned".

Please help me in fixing the issue.

Regards,

Shano

Hi,

FIELD-SYMBOLS: <f_itab1> LIKE line of it_vbak,

<f_itab2> LIKE line of it_vbap.

This will solve the issue.

Hi Mukesh,

Thanks for the reply. Everything is fine with Field-Catalog.And before looping I am sorting both the tables.But I don't understand why <f_itab1> is getting assigned and it's not happening with <f_itab2>.

Hi,

Use

FIELD-SYMBOLS: <f_itab1> TYPE any,

<f_itab2> TYPE any.

Hi Mohaiyuddin,

I tried in that way also but still it is the same problem. And one more thing I forgot to add is I am using ECC 6.0.

Hi,

Syntavtically your program is correct. The way I see it you must have declared the field symbols wrongly . Send your detailed code

Hi Amit,

It is giving syntax error when I tried as you mentioned. I tried as below also:

FIELD-SYMBOLS: <f_itab1> TYPE ANY TABLE,

<f_itab2> TYPE ANY TABLE.

But still it <f_itab2> while using READ is getting assigned.

Hello,

I have some doubts on this stmt

vbeln = <f_itab1>-ww206

Can you tell me whats WW206 field ??

May be ur READ TABLE is failing & so <f_itab2> is not getting assigned. If u try to use this FS, you will get a dump.

BR,

Suhas

Hi,

Are you checking sy-subrc after READ TABLE ?

If READ TABLE fails and you are trying to access second field symbol <f_itab2> it will go to dump.

HI Shano,

One more thing I want to share with you is, You need to UNASSIGN the field symbol after coming out of loop.

More or less its like a clear or refresh we use for our internal table and variables.

Warm regards,

Abhishek

Hi Suhas,

Sorry, it's actually vbeln. The code is as below.

FIELD-SYMBOLS: <f_itab1> TYPE vbak,

<f_itab2> TYPE vbap.

Select * from vbak into table it_vbak.

select * from vbap into table it_vbap.

LOOP AT it_vbak ASSIGNING <f_itab1>.

READ TABLE it_vbap ASSIGNING <f_itab2>

WITH KEY vbeln = <f_itab1>-vbeln.

ENDLOOP.

Shano

Hi Mohaiyuddin,

Offcourse I am checking Sy-subrc.

Sorry for the obvious, but thought worth mentioning.

It will be good if you can post complete code. (along with definition of IT_VBAK and IT_VBAP)..The segment you are posting seems correct.

Mohaiyuddin

Hello,

Please provide the definition of ITAB1 & ITAB2. I think ur READ TABLE is failing. Did you check SY-SUBRC, is ur READ TABLE OK?

Hi Shano,

you should try this:


loop....

  read table it_vbap assigning <f_itab2> with key vbeln = <f_itab1>-ww206.
  if <f_itab2> is assigned.
*  do your stuff here
  endif.
endloop.

if you want to react on a not present key in it_vbap


loop....

  read table it_vbap assigning <f_itab2> with key vbeln = <f_itab1>-ww206.
  check <f_itab2> is assigned.
* do your stuff here
endloop.

if you just want to skip a loop cycle if the key is not present in it_vbap.

Ah and don't forget to unassign <f_itab2> after doing your stuff. If you had it assigned in the cycle before and in the current it's not possible to assign it to a new line it keeps the old one and you overwrite the fields.

Regards,

Benny
