Using OO Abap programming optimally

[Former Member]

Dear experts,

I developed a report purely on Object Oriented concepts.It works really fine.

Now my requirement is that in one of my module pool program i want to retrieve some data from that report itself

and show in my Input help. I deliberately made this report OO as i had anticipated that it will be required to me in future.

Now time has come.I want to call some method of the defined class.It is at this point that i am ignorant how to do.

Methodi want to call from different program is that

fetch_lc_info ()

Let me explain you the structure of program which i am willing to call.

[code]

report zsammrp01.

include zdata_definitions. //I definitions

include zselect_lc_params. // selection screen

start-of-selection.

include zmainlc. //main logic

• Class Declarations

data : ob_get_all_lcinfo type ref to get_lc_details.

data: ob_alv_print type ref to alvprint.

• Perform functionalities

end-of-selection.

create object ob_get_all_lcinfo.

ob_get_all_lcinfo->fetch_lc_info( ).

create object ob_alv_print.

ob_alv_print->print_details( ).

end-of-selection.

[/code]

Let me show the zmainlc where i defined classes.

[code]

class get_lc_details definition.

public section.

methods: fetch_lc_info.

endclass.

class get_lc_details implementation.

method fetch_lc_info.

select a_{ebeln a}ebelp b_{ekgrp a}werks a_{menge a}meins

b_{bedat a}matnr a_{txz01 a}netwr b_{waers b}wkurs a_{netpr a}zztest a_{zzlcbt b}lifnr

from ekko as b inner join ekpo as a on

( a_{ebeln = b}ebeln ) into table t_all_lcs where b~bsart like 'IM%'.

some other manipulation on this table done..............

endmehod.

[/code]

Hi Aditya,

from your explanation, i get that you defined and implemented your classes locally.

To use local classes from outside their context is not supported, (though not impossible).

Instead, you can convert your local classes to global ones by accessing them by SE24 , using the import feature from the menu. Once they are globally defined, you can use them with every Program you like.

(Besides, there is an OO Forum)

if not impossible plz tell me that way as i am not interested to create any Z object in my system.Its prohibited.

Hi Aditya,

the issue has been discussed in the OO forum. Take a look here

In addition, it would be wise to put your classes into separate includes, so you'd just have to include them to ypour prog. This is the original idea of includes, to reuse them elesewhere.
