How to call a Method in a Program?

[Former Member]

Hello,

I am very new to the ABAP world. I have been given a task to call a method if_hrbas_plain_infotype_access~read_single from the class CL_HRBAS_PLAIN_INFOTYPE_ACCESS in a program to see if we can use it to display some employee information. I don't know how to call a method in a program. Can somebody please provide me some pseudo code or instructions?

Thanks.

In the same way you call a FM. Click on button Pattern, then give the method name you want to call.

Thanks for the response. However, I don't know how to call a FM as well. I am looking for some syntax or pseudo code. Sorry, if it is a basic question.

Thanks.

As I have said, press the pattern button from your editor. Their you will get the option. Or search net to get step by step details.

Hi Shan,

go to your program Se38 or from where you want to call method.

then in application tool bar, one pushbutton called 'PATERN ' is there. click that.

then one pop-up will come, within pop-up select 'abap object patern', radio button. then enter.

select call method radiobtton & then give the class name & method of that class which you want to called.

for class see tr. se24.

Hi,

Either you can use the patterns, or if you can simply type

CALL METHOD (CLASS_NAME)=>(METHOD NAME)

EXPORTING

IMPORTING .

Use F1 on 'Call method' to get more details.

Just follow the navigation provided below to call method from program.

Go to se38 transaction---> Open your program----> press ctrl+f6 (or) PATTERN button on the toolbar--->select ABAP OBJECT PATTERNS----> select CALL METHOD---> enter the method you want to call and hit enter.

Hi,

Click on the Pattern button (or ctrl+f6) in se38, choose "ABAP Object Patters" and click on u201Centeru201D button.

It will open an other window

Enter the Class as if_hrbas_plain_infotype_access and

enter the method as read

and again press enter...

The code is ready

Hope this helps.

Thanks

Hi Shan,

here is the code to call a method. while calling the method Instance as 'r_info' which is the type reference to class as specified.

pass the values to exporting parameters plvar,otype,objid...etc according to the requirement

infotypes: 0002.   " creates an internal table p0002.
data:

 r_info type ref to CL_HRBAS_PLAIN_INFOTYPE_ACCESS.
 
 TRY.
 CALL METHOD r_info->if_hrbas_plain_infotype_access~read
   EXPORTING
     plvar           =  
     otype           =
     objid           =
     istat           =
     infty           =
*     SUBTY           =
     begda           =
     endda           =
     no_auth_check   =  'X'
     message_handler =
   IMPORTING
     PNNNN_TAB       = P0002 
*     HRTNNNN_TAB     =
*     IS_OK           =
     .
  CATCH CX_HRBAS_VIOLATED_ASSERTION .
 ENDTRY.

LOOP AT P0002.
      WRITE:/
        P0002-VORNA,
        P0002-NCHMC,
        P0002-NACHN.

Hi,

From the ABAP editor (SE38) press the PATTERN button or press Control+F6.

Then select the radiio-button ABAP Object Patterns and then continue.

Next put in the Class/Interface name as - CL_HRBAS_PLAIN_INFOTYPE_ACCESS

and the Method name as - if_hrbas_plain_infotype_access~read_single and then click continue.
