read fields from dynamic table

[Former Member]

Hello everyone,

I'm a BW-guy with some ABAP background, but it has been a while since I've used field symbos. I'm writing an enhancement for a BI-extractor using a badi. This is the situation:

I have a dynamic table <t_data> over which I need to loop to change data. The fields I need to change are in another table, t_fields. I've written the following code, but in <fieldname>, I get the value of temp instead of the value in <s_data>-fieldname.

-

---

LOOP AT <t_data> INTO <s_data>.

LOOP AT t_fields INTO s_fields.

concatenate '<s_data>-' s_fields-fieldname into temp.

ASSIGN temp TO <fieldname>.

ENDLOOP.

ENDLOOP.

-

---

for example a possible result is:

<fieldname> = '<s_data>-calday' in stead of '01.01.2009'

Can anyone tell me what I've been doing wrong? Your help is greatly appreciated.

Hi,

Try this

LOOP AT <t_data> INTO <s_data>.
   LOOP AT t_fields INTO s_fields.
       assign component s_fields-fieldname of structure <s_data> to <fieldvalue>.
      <fieldvalue> =  "...here <fieldvalue> should have '01.01.2009' 
   ENDLOOP.
ENDLOOP.

Hi,

You are assinging to the temp.

BUt after that modify the main internal table by trtansporting the field which you have changed.

then only it will be updated.

Please revert for any help.

Hi,

Please let me know if I am clear on this.

You have two internal tables, itab1 and itab2. You would like to change the value of field (say fld1) in itab1. This fld1 value is available from fld in itab2.

If this is the situation, following is the code.

FIELD-SYMBOLS: <w_tab1> TYPE ty_tab1.
DATA:                   w_tab2     TYPE  ty_tab2.

LOOP AT itab1 ASSIGNING <w_tab1>.
  READ TABLE itab2 into w_tab2 WITH KEY
                               fldkey = <w_tab1>-fldkey.
  IF sy-subrc EQ 0.
    <w_tab1>-fld1 = w_tab2-fld.
  ENDIF.
ENDLOOP.

This is it. Table itab1 will be changed.

Let me know if this works or if your issue is different.

Regards,

Sourav
