Hi,

Please try these ...


data: it_mseg type table of mseg,
      it_mkpf type table of mkpf.
 
data: wa_mseg type mseg,
      wa_mkpf type mkpf.

or

types: begin of ty_itab,
         <your fields>.
        end of ty_itab.

data: itab type table of ty_itab,
      wa_itab type ty_itab.

Regards,

Ferry Lianto

hi,

Corrrect way of declaration? what do u mean by this.

ways to declare internal tables.

1) if you want to create a intenal table same as a standard table in the database then

data : itab like standard table of vbak with header line.

2) if you want to have your own structure to your internal table the.

delcare types : this is how you shold do most of the times. to be more professional

types : begin of ty_tab,

field1,

field 2,

end of ty_tab.

data : x_tab type ty_tab.

data: itab like standard table of x_Tab with header line.

3) data : begin of itab occurs 0,

field1,

field 2,

end of itab.

with object oriented programming type 3 declartion is ruled out and also with header line specification is not possible in this oops scenerio you have to do like this

data : itab like standard table of vbak.

x_tab like vbak.

Thanks

TYPES: BEGIN of my_type,

field1(1),

field2(1),

END OF my_type.

DATA i_table like standard TABLE OF my_type.

DATA wa_table like my_type.

first declare type and declare internal table with out header line and work area

TYPES : BEGIN OF ty_tab

Fields names

END OF ty_tab.

DATA: itab TYPE STANDARD TABLE OF ty_tab INITIAL SIZE 0. " internal table

DATA: wa TYPE ty_tab. " Work Area

If u want to use Field-symbols, then

FIELD-SYMBOLS : <fs> type ty_tab.

and use like

LOOP AT itab ASSIGNING <fs>.

process <fs>.

ENDLOOP.

Reward if useful
