Hi,

You can build the Field catalog in this way..

You need to find the number of fields you need to have in the field catalog..

DO N TIMES.  " N is the count of the fields in the table

CONCATENATE 'REM' SY-INDEX INTO FIELD.

APPEND field to field catalog.

ENDDO.

Hi ,

You can Achieve this by using field symbols.

DO n times.

assign field value to field symbol.

and if it is found then you move and append this to a dynamic internal table.

Please let me know fi you still need any help.

Thanks and regards,

Rajeshwar.
