Dynamic select columns

[Former Member]

I have a Z_Temp table which has 51 colums like NKEY, NTEM001, NTEM002.... NTEM050. This table will be joined on Z_JOIN table (columns NOTE, TXT) ON NTEM*= NOTE.

( NTEM001 = NOTE, NTEM002 = NOTE, NTEM003 = NOTE .....)

For all NTEM* columns that are not initial, I need to get TXT column from Z_JOIN table and send it to a Sapscript form.

What is the best approach in doing this ?

Thanks.

First make a select from the first table.

The make a second select from the other table.

Loop at first table.

read the second table with key values

move the two columns to a final itab.

append final itab.

endloop.

I got until the loop at first table. How do I check if the 50 columns are initial or not. I don't want to give 50 IF statements. I would like to do something like this

v_counter = 1

DO 50 TIMES. * this will return 1 row

v_column = 'itab-NTEM'

v_column+15(3) = v_counter.

IF NOT v_column IS INITIAL. *** This line of code fails

(some code here)

ENDIF.

v_counter = v_counter + 1.

ENDDO.

Any ideas.

Horizontal scrolling in a single table record is possible with the DO...VARYING... construct, please read the F1 help on the same.

something like this

DATA:

ntem TYPE z_temp-ntem001

DO 50 TIMES VARYING ntem FROM ntem001 NEXT ntem002.

IF ntem IS NOT INITIAL.

your code.

ENDIF.

ENDDO
