Reading internal table with dynamic fields

Former Member — Thu, 13 Mar 2008 15:04:51 GMT

Hi Gurus,

I'm trying to read an internal table with dynamic field.

Here is the scenario:

1) In the main program I have an internal table itab with fields a, b ,c ,d marked with X's

2) I call a perform in one of my modules and pass the field name of the internal table itab

in parameter p_field.

3) This is where I'm stuck. How do I read or even loop thru the internal table passing the field name in a parameter?

FORM get_field USING P_field

CHANGING P_HIDE_COL.

Read the table with key p_det_scrnm

Loop at internal table ITAB.

ENDFORM. " get_field

Any suggestion on the syntax?

Tnx

hi ,

I believe the column can be dynamic ...but not the entire WITH KEY..

Check this Example..

code

DATA: itab TYPE STANDARD TABLE OF mara.

DATA: wa TYPE mara.

DATA: where(72).

DATA: where1(72).

Populate.

wa-matnr = 'TEST'.

wa-mtart = 'M1'.

APPEND wa TO itab.

Where clause

where = 'MATNR'.

where1 = 'MTART'.

READ TABLE itab INTO wa WITH KEY (WHERE) = 'TEST'

(WHERE1) = 'M1'.

IF sy-subrc = 0.

WRITE: / 'found'.

ENDIF.

[/code]

regards,

venkat.

Thank you , thank you Venkat,

It worked!!!!!!

Its weird 'coz I did try something similar before I went all crazy doing differenct things but it didn't work. I guess I must have messed up on some comma or period somewhere.
