types :begin of 1_tab,

pernr type pernr_d,

end of 1_tab.

I would say to always use a Table Type declaration when typing a TABLES parameter in the FORM statement. In this case...

types :begin of 1_tab,
       pernr type pernr_d,
       end of 1_tab,
       
       tt_1tab type table of 1_tab.

form some_form  tables p_itab type tt_1tab.

endform.

SAP recommends to always use table types in any intefaces, methods, function modules, and forms.

Hello ricardo arona ,

always use TYPES statement for defining the internal table or use like

DATA : <ITAB> TYPE TABLE of <STRUCTURE>.

Thanks,
