Calling Non- SAP applications from ABAP

[Former Member]

Hi ALL ,

How to call a Non-SAP ( applications written in other technologies) from ABAP.

Well for calling an application ( without callback) you can use fm - WS_EXECUTE

Example -

CALL FUNCTION WS_EXECUTE

EXPORTING PROGRAM = 'winword'

launches MS Word.

Now if you want to execute them with callback then - you will have to go for OLE automation. The prerequisite is the Application has to support the OLE automation framework. You can do them like this -

DATA : H_EXCEL TYPE OLE2_OBJECT,
       H_WRKBK TYPE OLE2_OBJECT,

* Create Excel Application.
  CREATE OBJECT H_EXCEL  'Excel.Application'. " This is the CLSID.
  CHECK SY-SUBRC EQ 0.

* Get the Workbook object.
  CALL METHOD OF H_EXCEL 'Workbooks' = H_WRKBK.
  CHECK SY-SUBRC EQ 0.

Hope it helps.

HI SKC ,

Thanks for your reply .Sorry , i think i havent explained the question correctly .

i have to make a call to a NON -SAP application which is on a different system .I dont have to launch a application .i just have to call a function .

The function u want to call has to be RFC enabled ( check the attributes tab in SE37 u ll find a radio button with the same caption).

In SM59 , U will have to define a RFC destination for the Target system - here u will define the IP address, User ID etc.

Then u can call the FM like this

CALL FUNC 'func' DESTINATIOn dest

EXPORTING....

You can refer to the help of CALL FUNCTION , it will give u all the details.

Revert back in case of problems.

Hi SKC,

Thanks for your reply .My Function is not in ABAP, It is written in NON-SAP techanology .

I did not understand the point you have mentioned.

>><b>The function u want to call has to be RFC enabled ( check the attributes tab in SE37 u ll find a radio button with the same caption).</b>

Do i have to create some equavalant function module for the NON-SAP function in ABAP .If so how to do that .

So u want to call a function that is -

1. In a diff system.

2. Non SAP.

Well, i have told u about calling a function of a diff system. It has to support OLE automation framework. There is no way u can call a function of a DLL or an EXE.

My previous codes showed the ways of calling functions of MSExcel.

Now RFC enabled FMs are the FMs ( use transaction SE37 for viewing Function Modules ) those can be called from outside system. For example u can call RFC_GET_MATERIAL_DATA from ur MS Excel file or any other application. For this Function module , if u go to the attribute tab, u ll find that it is RFC enabled.

It depends highly on ur target system - if it is as simple as Java Script - then it can be done - if it is C/C++ then there is no way u can call them from ABAP.
