Using BO method in function.

Former Member — Wed, 15 Jun 2005 07:11:42 GMT

I would like to use Business object method in my function. In BOR browser is e.g. object Flight object type SFLIGHT. I have tried to call this object method with:

FLIGHT=>create( ).

and

SFLIGHT=>create( ).

and compiler response is always

Class not known.

What should I do??

Regards

Have you ever heard of the SWC-macros?!

First you have to instantiate your SFLIGHT with

SWC_CREATE_OBJECT <field to hold obj instance> <obj type> <key of obj>

. After this you have access to all attributes and methods of your SFLIGHT instance.

Then create the object container with

SWC_CONTAINER <container>

Call the method you want with

SWC_CALL_METHOD <filed to hold obj instance> <name of method> <container>

Thanks for answer:)

I must this tutorial studying a little

I have heard about SWC macros but I unfortunately can't use it:( I know, i should <object> include. But when I try do it (add to includes node in function module) i have a message:

Object <OBJECT> already exists

then when i try use macro:

Statement SWC_GET_ELEMENT not defined.

What is not correct?

Please post your code if possible. That would make safe a lot of time spent on speculations otherwise!

Hi Mike

I have tried e.g. with code

FUNCTION Z_BO_TEST.
*"----------------------------------------------------------------------
*"*"Lokale Schnittstelle:
*"----------------------------------------------------------------------

DATA: flight TYPE SWC_OBJECT.

SWC_CREATE_OBJECT flight SFLIGHT '1111'.
SWC_CONTAINER cont.
SWC_CREATE_CONTAINER cont.
SWC_SET_ELEMENT cont <par1> <Value1>.
.
.
.
SWC_CALL_METHOD flieght getlist cont.
ENDFUNCTION.

That is function module in function group. I can't this function compile (try include object). Where and how can i do it?

regards

bogdan

What is the object type (SWO1) of your 'FLIGHT' object?

Re: Using BO method in function.

Former Member — Wed, 15 Jun 2005 14:24:24 GMT

I dod not check this code, but this is the way it should work:


* structure to save the key to instantiate SFLIGHT
* ATTENTION: This structure must be filled before 
* instantiating the object !!!!
DATA: BEGIN OF gs_sflight_key,
				mandt LIKE sflight-mandt,
				carrid LIKE sflight-carrid,
				connid LIKE sflight-connid,
				fldate LIKE sflight-fldate,
			END OF gs_sflight_key.

DATA: go_sflight TYPE swc_object.

* generate swc container
SWC_CONTAINER gc_container.

* instantiate object GO_SFLIGHT with key GS_SFLIGHT_KEY
SWC_CREATE_OBJECT go_sflight 'SFLIGHT' gs_sflight_key.

* instantiate container
SWC_CREATE_CONTAINER gc_container.

* call method DISPLAY of obj instance GO_SFLIGHT within
* conatiner GC_CONTAINER
SWC_CALL_METHOD go_sflight 'DISPLAY' gc_container.

Please don't define a new include in your function group program.

Just put the include statement

INCLUDE <cntn01>.

in your function group's top include ( XXXTOP include...)...Where you declare global data ...

Hi Mike

I can't compile this example

I have written:

*&---------------------------------------------------------------------*
*& Module pool       ZZZZZTEST                                         *
*&                                                                     *
*&---------------------------------------------------------------------*
*&                                                                     *
*&                                                                     *
*&---------------------------------------------------------------------*

include <object>.

* structure to save the key to instantiate SFLIGHT
* ATTENTION: This structure must be filled before
* instantiating the object !!!!
DATA: BEGIN OF gs_sflight_key,
				mandt LIKE sflight-mandt,
				carrid LIKE sflight-carrid,
				connid LIKE sflight-connid,
				fldate LIKE sflight-fldate,
			END OF gs_sflight_key.

DATA: go_sflight TYPE swc_object.

* generate swc container
SWC_CONTAINER gc_container.

* instantiate object GO_SFLIGHT with key GS_SFLIGHT_KEY
SWC_CREATE_OBJECT go_sflight 'SFLIGHT' gs_sflight_key.

* instantiate container
SWC_CREATE_CONTAINER gc_container. "!!!!!!!!!!!!!

* call method DISPLAY of obj instance GO_SFLIGHT within
* conatiner GC_CONTAINER
SWC_CALL_METHOD go_sflight 'DISPLAY' gc_container.

and i have got a compiler message:

"Statement is not accessible "

in line with "!!!!!!!!!!!!!)

I have superseded macros with his code and that works.

I have no idea what exactly should I do to use this macros

Than do not execute the following line


SWC_CREATE_CONTAINER gc_container.

Just comment it out.

What happens now?!

Re: Using BO method in function.

Former Member — Thu, 16 Jun 2005 13:21:30 GMT

you might check my last response and try that also.

Further, I am not sure you first wrote the code in a FM and then a module pool..

In case you are doing it in an FM ...

Call the include <cntn01> in your top include along with the global data declaration...

And also that cntn01> is sufficient for your work <object> is not required.

Hi Ram

excuse me, I have tried with function module and program

In program I can use include at the beginning my code. Where and how should I do that in function group?

Would you like to explain me that exactly?

Hi Mike

selfsame error occured in next line

Re: Using BO method in function.

Former Member — Thu, 16 Jun 2005 13:51:44 GMT

You have to include <cntn01> in the top include of your function group!
