Dynamic Work Area - fields

Former Member — Thu, 16 Feb 2006 08:12:26 GMT

HI SDN COMMUNITY..!!

I HAVE TO USE THE WA_SEKPO-FIELDNAME DYNAMICALLY..

DATA: BEGIN OF WA_SEKPO,
      EBELN TYPE EBELN,
      BRTWR TYPE BRTWR,
      EFFWR TYPE EFFWR,
      MENGE TYPE MENGE,
      END OF WA_SEKPO.

DATA: SEKPO LIKE TABLE OF WA_SEKPO.

DATA: VAR_FNAME TYPE STRING.


FIELD-SYMBOLS: <FS> TYPE ANY.

STRUCTURE OF <b>EDITPOS</b>(INTERNAL TABLE)

****************************************

|4500016340 |EKPO |BRTWR | 26 | 11

|4500016340 |EKPO |EFFWR | 25 | 12

|4500016340 |EKPO |MENGE | 22 | 13

INTERNAL TABLE :

<b>EDITPOS</b> CONTAINS VALUES FOR : BRTWR

EFFWR

MENGE

IT MAY CONTAIN VALUES FOR MORE FIELDS.

NOW PROBLEM IS

I HAVE TO UPDATE MY INTERNAL TABLE : SEKPO

FOR FIELDNAMES : BRTWR

EFFWR

MENGE

BUT I DONT HAVE TO HARD CODE IT FOR EACH FIELD.

PLEASE CHECK, HOW THIS CAN BE ACHIVED?
WA_SEKPO-BRTWR = WA_EDITPOS-F_NEW.

PLEASE UPDATE THE CODE:

LOOP AT EDITPOS INTO WA_EDITPOS.

           ASSIGN WA_EDITPOS-FNAME TO <FS>.

           CONCATENATE 'WA_SEKPO-' <FS> INTO VAR_FNAME.

           WA_SEKPO-(<FS>)  = WA_EDITPOS-F_NEW.

*       MODIFY TABLE SEKPO FROM WA_SEKPO
*          TRANSPORTING <FS>.

ENDLOOP.

HELP WILL BE APPRICIATED

THANKS IN ADVANCE

LOOP AT EDITPOS INTO WA_EDITPOS.

ASSIGN WA_EDITPOS-FNAME TO <FS>.

CONCATENATE 'WA_SEKPO-' <FS> INTO VAR_FNAME.

to be added

assign (VAR_FNAME) to <FS2>

<FS2> = WA_EDITPOS-F_NEW.

end of code to be added

MODIFY TABLE SEKPO FROM WA_SEKPO
TRANSPORTING <FS>.

ENDLOOP.

Create another field symbol <FS2> for this.

PLEASE BE CLEAR WHAT IS UR EXCAT REQUIREMNET.

to create table dynamically, there are many posts in form, pls earch.

also to create structure also dynamically there r many posts.

just place the topic and click on search

STRUCTURE OF EDITPOS(INTERNAL TABLE)

****************************************

|4500016340 |EKPO |BRTWR | 26 | 11

|4500016340 |EKPO |EFFWR | 25 | 12

|4500016340 |EKPO |MENGE | 22 | 13

LOOP AT EDITPOS INTO WA_EDITPOS.
IF WA_EDITPOS = 'BRTWR'.
  WA_SEKPO-BRTWR = WA_EDITPOS-F_NEW. 
  
  MODIFY TABLE SEKPO FROM WA_SEKPO
  TRANSPORTING BRTWR.


ELSEIF WA_EDITPOS = 'EFFWR'.

  WA_SEKPO-EFFWR = WA_EDITPOS-F_NEW. 

  MODIFY TABLE SEKPO FROM WA_SEKPO
  TRANSPORTING EFFWR.

ELSEIF WA_EDITPOS = 'MENGE'.
  WA_SEKPO-EFFWR = WA_EDITPOS-F_NEW. 

  MODIFY TABLE SEKPO FROM WA_SEKPO
  TRANSPORTING MENGE.
ENDIF.

ENDLOOP.

*******************************************

I AM TRYING TO ACHIEVE THE ABOVE FUNCTIONALITY DYNAMICALLY,

AS I AM UNAWARE OF ENTRIES IN Internal Table: EDITPOS.

It contains values: BRTWR/EFFWR/MENGE

But it may contain more,SO i cannot straight away HARD code it for modifying entries in SEKPO.

for which i have written the code:

LOOP AT EDITPOS INTO WA_EDITPOS.

ASSIGN WA_EDITPOS-FNAME TO <FS>.

CONCATENATE 'WA_SEKPO-' <FS> INTO VAR_FNAME.

WA_SEKPO-<FS> = WA_EDITPOS-F_NEW.

MODIFY TABLE SEKPO FROM WA_SEKPO
TRANSPORTING <FS>.

ENDLOOP.

But there it shown Error before Activating the code: that <fs> is not a component of work area wa_sekpo

WA_SEKPO-<FS>

that is the problem,How to assign fieldname to a work area Dynamically.

Vijay Raheja

hymavathi_oruganti — Thu, 16 Feb 2006 09:33:35 GMT

replace the folloeing

CONCATENATE 'WA_SEKPO-' <FS> INTO VAR_FNAME.

WA_SEKPO-<FS> = WA_EDITPOS-F_NEW.

with

CONCATENATE 'WA_SEKPO-' <FS> INTO VAR_FNAME.

VAR_FNAME = WA_EDITPOS-F_NEW.

Hello Vijay and Anand,

Assigning the variable name (a string!) to the field symbol is not the right thing to do, and will result in a short dump. You would have to assign the variable itself to the field symbol. I cannot see a way to do this dynamically. However here is a simple solution for your program, using a form:

LOOP AT editpos INTO wa_editpos.

CONCATENATE 'wa_sekpo' wa_editpos-fname INTO var_fname.

PERFORM assign_fs.

<fs> = wa_editpos-f_new.

...

ENDLOOP.

FORM assign_fs.

CASE var_fname.

WHEN 'EBELN'. ASSIGN wa_sekpo-ebeln TO <fs>.

WHEN 'BRTWR'. ASSIGN wa_sekpo-brtwr TO <fs>.

WHEN 'EFFWR'. ASSIGN wa_sekpo-effwr TO <fs>.

WHEN 'MENGE'. ASSIGN wa_sekpo-menge TO <fs>.

WHEN OTHERS. WRITE 'Illegal fieldname'.

ENDCASE.

ENDFORM.

Kind regards,

Michael

HI Michael Kraemer

Thanks for replying...But Problem is still there.

USING YOUR CODE.

WHEN 'EBELN'. 
ASSIGN wa_sekpo-ebeln TO <fs>.

<FS> WILL CONTAIN wa_sekpo-ebeln

and then

<fs> = wa_editpos-f_new.

<fs> will contain the value for EBELN in EDITPOS-F_NEW

BUT I NEED THE VALUE IN

<b>WA_SEKPO-EBELN = wa_editpos-f_new.</b>

***************************

problem is still there...

MODIFY TABLE SEKPO FROM <b>WA_SEKPO-EBELN</b>
TRANSPORTING EBELN.

Hello Vijay,

You wrote:

"<fs> will contain the value for EBELN in EDITPOS-F_NEW

BUT I NEED THE VALUE IN

WA_SEKPO-EBELN = wa_editpos-f_new."

But the value is there in wa_sekpo-ebeln already!! By assigning the value to the field symbol you are assigning it to the variable to which it points. The reason is that a field symbol is a placeholder for a variable, similar to a pointer.

Please pay attention to this difference:

1. ASSIGN wa_sekpo-ebeln TO <fs>.

This lets the field symbol <fs> be a placeholder for the variable wa_sekpo-ebeln. From now on everything that you do to <fs> happens to wa_sekpo-ebeln.

2. <fs> = wa_editpos-f_new.

This assigns the value in wa_editpos-f_new to the variable wa_sekpo-ebeln, because <fs> at present points to this variable.

Here is a simple example:

DATA city(10) TYPE c.

FIELD-SYMBOLS <fs> TYPE ANY.

ASSIGN city TO <fs>.

<fs> = 'HYDERABAD'.

WRITE city.

The output of this program is: HYDERABAD

Kind regards,

Michael

Thanks Folks.!!

Anand's reply is perfect.

LOOP AT EDITPOS INTO WA_EDITPOS.


           ASSIGN WA_EDITPOS-FNAME TO <FS>.
           CONCATENATE 'WA_SEKPO-' <FS> INTO VAR_FNAME.

<b>           ASSIGN (VAR_FNAME) TO <VALUE>.

           <VALUE> = WA_EDITPOS-F_NEW .</b>

     ENDLOOP.

ASSIGN (VAR_FNAME)TO <FS>

THIS PERFORMS THE SAME TASK AS :

ASSIGN WA_SEKPO-BRTWR TO <FS>
