class method

Former Member — Mon, 16 Jul 2007 12:58:54 GMT

Hi,

I created code like this:

CLASS item DEFINITION.

PUBLIC SECTION.

METHODS:

constructor IMPORTING matnr type matnr

sstuf type sstuf,

write_result.

PROTECTED SECTION.

DATA: matnr type matnr,

maktx type maktx.

METHODS: get_maktx,

get_stuff.

endclass.

class item implementation.

method constructor.

data: obiekt type ref to item.

me->matnr = matnr.

"me->sstuf = sstuf.

call method: get_maktx, get_stuff.

call method obiekt->write_result.

method get_maktx.

select single maktx from mara into maktx where matnr = 'A103'.

ENDMETHOD.

method get_stuff.

select single stuff from mara into stuff where matnr = 'A103'.

endmethod.

method write_result.

write: maktx, stuff.

uline.

endmethod.

endclass.

After F8 i get info that: "statement endmethod missing".

What should i change in code?

Regards,

Joanna

Hi,

So is this a FORM or a method. You open with FORM, but close with END METHOD and END CLASS.

If it is a FORM, then end with an ENDFORM. If it is a method, then you must begin with a METHOD statement.

Well, your first problem is that you are missing the ENDMETHOD for your CONSTRUCTOR method, but you will have other problems as well.



class item implementation.
method constructor.
data: obiekt type ref to item.

me->matnr = matnr.
"me->sstuf = sstuf.

call method: get_maktx, get_stuff.
call method obiekt->write_result.

ENDMETHOD      .    " <------ RIGHT HERE

method get_maktx. 
select single maktx from mara into maktx where matnr = 'A103'.
ENDMETHOD.
