Re: Runtime error ITAB_DUPLICATE_KEY due to declaration of internal table type hashed table

you can do like this :

LOOP AT <first_table>        INTO wa.     ls_vbkd_hashed-bstkd = wa-bstkd." Because at new make other fields *
AT NEW VBELN.     ls_vbkd_hashed-vbeln = <wa>-vbeln.     INSERT ls_vbkd_hadhed          INTO TABLE lt_vbkd_hashed.
ENDAT.
ENDLOOP.
