ABAP 750 - optimizing code

[SimoneMilesi]

Hi all

I have this little piece of code where I receive as input a table (WORKING_TAB) and I've to retrieve data from DB using as partial value the field KNUMA_AG of given table

This is how I managed to do it, but I totally dislike the loop - select appending part

 METHOD get_ips.
    TYPES: BEGIN OF ty_vakey,
             vakey TYPE /irm/ipbckcitm-vakey,
           END OF ty_vakey.
    TYPES: tty_vakey TYPE STANDARD TABLE OF ty_vakey WITH DEFAULT KEY.
    CLEAR ips.
    DATA(keys) = VALUE tty_vakey( FOR row IN working_tab
                                ( vakey = '%' && row-knuma_ag && '%' ) ).
    LOOP AT keys INTO DATA(key).
      SELECT * APPENDING CORRESPONDING FIELDS OF TABLE ips
                     FROM /irm/ipbckcitm
                     WHERE vakey LIKE key-vakey.
    ENDLOOP..
  ENDMETHOD.

Can you suggest a more elegant way to do it?

Thanks!

I think you can use range table for this.
Change tty_vakey to "range" structure (sign+option+low+high fields).
In VALUE fill:

sign = 'I'
option = 'CP'
low = '*' && row-knuma_ag && '*'

I'm a.... not so smart person >_<
I didn't tink about ranges!
