Declaration Error for Object orient Programming

Former Member — Tue, 27 Nov 2007 16:36:21 GMT

Hi All,

can any tell me how to export Select-options .This is an object oriented question

include ztest.

select-options : s_werks for marc-werks obligatory,

s_matnr for mara-matnr obligatory.

data : O_object type ref to lcl_test.

start-of-selection.

CREATE OBJECT O_object EXPORTING IM_S_WERKS[] IN S_WERKS[]

IM_S_LGORT[] in s_matnr[].

Above statment is the problem

This is my include ztest.

CLASS lcl_test DEFINITION.

METHODS constructor IMPORTING IMWERKS[] TYPE MARC-WERKS

imLGORT[] TYPE MARD-LGORT.

Above statment is the problem

endclass.

Can anyone tell me how to declare

Thanks

Adi

You have to declare local types (e.g. werks_sel_type and lgort_sel_type) that has the same structure of s_werks and lgort_sel_type as a standard table.

CLASS lcl_test DEFINITION.

METHODS constructor IMPORTING imwerks TYPE werks_sel_type.
imLGORT TYPE lgort_sel_type.

Then

CREATE OBJECT O_object EXPORTING IM_S_WERKS = S_WERKS

IM_S_LGORT = s_matnr.

I suggest you read the ABAP help for select-options to see how they are actually defined internally.

Also look carefully in the ABAP help for how to declare parameters for constructors and methods. [] is not valid!

Hi Matthew,

I declared like this

types : begin of iwerks ,

SIGN(2) type c,

OPTION(2) type c,

low(4) type c,

high(4) type c,

end of iwerks.

METHODS constructor IMPORTING IM_S_WERKS TYPE iwerks.

start-of-selection.

CREATE OBJECT O_IMARD EXPORTING IM_S_WERKS = S_WERKS.

This one gives me an error

saying im_s_werks is not compatible with s_werks.

Let me know

Thanks

Hi Rich,

This is what i have

start-of-selection.

CREATE OBJECT O_IMARD EXPORTING IM_WERKS = S_WERKS[].

CLASS lcl_par DEFINITION.

public section.

TYPES: t_werks TYPE RANGE OF werks.

DATA: r_werks TYPE t_werks.

*types : begin of iwerks ,

*SIGN(2) type c,

*OPTION(2) type c,

*low(4) type c,

*high(4) type c,

*end of iwerks.

METHODS: constructor IMPORTING im_werks TYPE t_werks.

endclass.

CLASS lcl_par implementation.

METHOD constructor.

r_werks = im_werks.
