how to get the fields of an internal table?

Posted on Oct 17, 2006 at 05:35 AM 71 Views

Hi experts!

Is there a standard function module that gets the fieldname, length, and data type of an internal table?

I was trying to use display_internal_tables but it's not working.

Thanks!

    HI,

    Declare a work area in the top include and you can create the internal table based on that in your subroutine..

    Call the GET_COMPONENT_LIST with the Work area name..It will get you the components...

    EX:

    DATA: BEGIN OF WA,

    VBELN LIKE VBAK-VBELN,

    POSNR LIKE VBAP-POSNR,

    END OF WA.

    REPORT YRT_TEST1 line-size 500.

    data:

    Fields type i,

    begin of fieldlist occurs 0,

    no like RSTRUCINFO,

    end of fieldlist,

    begin of itab occurs 0,

    f1 TYPE C,

    f2,

    f3,

    end of itab.

    CALL FUNCTION 'GET_COMPONENT_LIST'

    EXPORTING

    program = 'YRT_TEST1'

    fieldname = 'ITAB'

    tables

    components = fieldlist

    .

    describe table fieldlist lines fields.

    write:/ fields.

    Regards,

    Laxmi.
