Calling BAPI from VB with ECC 6.0

I have a Visual Basic 6 application that calls some standard BAPI's in a SAP R/3 system using Frontend 4.6d in order to upload data. It also calls some custom RFC enabled ABAP to download data.
We are upgrading to ECC 6.0 with SAP GUI 7.1.
Can anyone tell me if I can still call BAPI's from VB6 or will I need to upgrade to VB.net? Are there any changes to references in VB that I will need to make?
Thanks!!

Well I could never figure out a way to call a BAPI from VB6 with ECC 6. I ended up creating a VB.net dll using the SAP connector to call the BAPIs. I could then call the dll from my existing VB 6 program. That cut down on the recoding that I had to do.

Hi Jagrut,
BAPI stands for Business API(Application Program Interface).
A BAPI is remotely enabled function module ie it can be invoked from remote programs like standalone JAVA programs, web interface etc..
You can make your function module remotely enabled in attributes of Function module but
A BAPI are standard SAP function modules provided by SAP for remote access. Also they are part of Businees Objest Repository(BOR).
BAPI are RFC enabled function modules. the difference between RFc and BAPI are business objects. You create business objects and those are then registered in your BOR (Business Object Repository) which can be accessed outside the SAP system by using some other applications (Non-SAP) such as VB or JAVA. in this case u only specify the business object and its method from external system in BAPI there is no direct system call. while RFC are direct system call Some BAPIs provide basic functions and can be used for most SAP business object types. These BAPIs should be implemented the same for all business object types. Standardized BAPIs are easier to use and prevent users having to deal with a number of different BAPIs. Whenever possible, a standardized BAPI must be used in preference to an individual BAPI.
The following standardized BAPIs are provided:
Reading instances of SAP business objects
GetList ( ) With the BAPI GetList you can select a range of object key values, for example, company codes and material numbers.
The BAPI GetList() is a class method.
GetDetail() With the BAPI GetDetail() the details of an instance of a business object type are retrieved and returned to the calling program. The instance is identified via its key. The BAPI GetDetail() is an instance method. BAPIs that can create, change or delete instances of a business object type
The following BAPIs of the same object type have to be programmed so that they can be called several times within one transaction. For example, if, after sales order 1 has been created, a second sales order 2 is created in the same transaction, the second BAPI call must not affect the consistency of the sales order 2. After completing the transaction with a COMMIT WORK, both the orders are saved consistently in the database.
Create( ) and CreateFromData! ( )
The BAPIs Create() and CreateFromData() create an instance of an SAP business object type, for example, a purchase order. These BAPIs are class methods.
Change( )
The BAPI Change() changes an existing instance of an SAP business object type, for example, a purchase order. The BAPI Change () is an instance method.
Delete( ) and Undelete( ) The BAPI Delete() deletes an instance of an SAP business object type from the database or sets a deletion flag.
The BAPI Undelete() removes a deletion flag. These BAPIs are instance methods.
Cancel ( ) Unlike the BAPI Delete(), the BAPI Cancel() cancels an instance of a business object type. The instance to be cancelled remains in the database and an additional instance is created and this is the one that is actually canceled. The Cancel() BAPI is an instance method.
Add<subobject> ( ) and Remove<subobject> ( ) The BAPI Add<subobject> adds a subobject to an existing object inst! ance and the BAPI and Remove<subobject> removes a subobject from an object instance. These BAPIs are instance methods.
ex BAPI:
API_SALESORDER_CREATEFROMDAT1
BAPI_SALESORDER_CREATEFROMDAT2

EG::
Here is the step by step procedure for creating BAPIs.
There are 5 different steps in BAPI.
- Create BAPI Structure
- Create BAPI Function Module or API Method.
- Create BAPI object
- Release BAPI Function Module.
- Release BAPI object.
Step1. Creating BAPI Structure:
- Go to <SE11>.
- Select Data Type & Enter a name.
- Click on Create.
- Note: Always BAPI should be in a development class with request number (Not Local Object).
- Select Structure & hit ENTER.
- Enter the fields from your database. Make sure that the first field is the Primary Key Field.
- Then SAVE & ACTIVATE.
Step 2. Creating BAPI module:
- Enter TR.CODE <SE37>.
- Before entering any thing, from the present screen that you are in, select the menu
Goto -> Function Groups -> Create Group.
Enter a name (Note: This name Must start with ZBAPI)
Let this screen be as it is and open another window and there, enter TR.CODE <SE80).
Click on the Third ICON that says Inactive Objects.
Select the group that you just created and click on Activate.
Notice that the group you created will disappear from the list of inactive objects.
- Go back to ><SE37> screen and enter a name and hit <ENTER>. Then enter the group name that you just created and activated.
NOTE: When you release a function module the respective group will be attached to that particular application. It cannot be used for any other application. NEVER include an already existing group that is attached to another module.
Now click on the first Tab that says [ATTRIBUTES] and select the radio button that says remote-enabled module since we will be accessing this from any external system.
Then click on the second tab that says [IMPORT].
Enter a PARAMETER NAME, TYPE and the structure you created in the first step. Also select the check box Pa. All remotely enabled functional modules MUST be Pa enabled, where Pa means Passed by Value and if you dont select Pa, then that means it will be passed by reference..
Then click on tab that says [EXPORT].
Enter the following as is in the first three fields
RETURN TYPE BAPIRETURN (These 3 field values are always same)
Here also select Pa meaning Pass by value.
Note: BAPIRETURN contains structure with message fields.
Then SAVE and ACTIVATE.
Step 3. Creating BAPI object:
- Enter Tr.Code <SWO1> (Note. It is letter O and not Zero).
- Enter a name and then click on create. Enter details.
NOTE: Make sure that that Object Type and Program name are SAME.
- Enter Application M, if you are using standard table Mara. If you are using your own database then select Z at the bottom.
- Then hit <ENTER>.
- Now we have to add Methods. High light METHODS and then select the following from the menu:
Goto Utilities -> API Methods -> Add Methods.
- Enter function Module name and hit <ENTER>.
- Select the second FORWARD ARROW button (>)to go to next step.
- Check if every thing looks ok and again click on FORWARD ARROW button (>).
- Then select YES and click on <SAVE>.
- Now on a different screen goto TR.CODE <SE37>. Enter Function Module name and select from the top menu Function Module -> Release -> Release.
- Goback to TR.CODE <SWO1>.
Here select the menu combination shown below in the same order.
- Edit -> Change Release Status -> Object Type Component -> To Implemented.
- Edit -> Change Release Status -> Object Type Component -> To Released.
- Edit -> Change Release Status -> Object Type -> To Implemented.
- Edit -> Change Release Status -> Object Type -> To Released.
- Then click on <SAVE>.
- Then click on Generate Button (4th button from left hand side looks like spinning wheel).
- Then Click on the button that says PROGRAM to see the source code.
To check if this is present in work flow goto TR.CODE <BAPI>.
Here it shows business object repository.
- First click on the middle button and then select ALL and hit ENTER.
- Goto tab [ALPHABETICAL] and look for the object that you created. This shows that the BAPI object has been created successfully
Reward pts if found usefull :)

How to call BAPI from R/3 system

hi,
i am doing small application by using Model. that is calling BAPI from R/3 system. but i am not able to get data from the back end system. please suggest me regarding this problem
thanx
tanvi

steps:
1) create Model
2) bind Model to component controller ( you can use data modeler.) 2.1) open data modeler; if your model is not there, you can add by clicking add existing model;
2.2) create data link between model and controller, it will open map dialog.
2.3) click and drag BAPI_xxx_Input to context of controller and select all nodes inside
- if there is any duplicate nodes, just rename it.
3) map context to view controller
3.1) map input parameters separately ( which takes value for IMPORT to BAPI. select only that fields
3.2) do map for output (exact node which contains BAPI output)
coding:
1) in component controller you need to instantiate model and bind to context
BAPI_xxx_Input my_input = new BAPI_xxx_input();
wdContext.nodeBAPI_xxx_Input my_input().bind( my_input);
2) create a method in the component controller so that we can execute it from any of views used.
try{
wdContext.currentBAPI_xxx_Input my_input().modelObject().execute();
}catch(WDRFCException e) {
e.printStackTrace();
wdContext.node<ExactOutput>().invalidate();
// this stmt will reflect new values
3) Go to view and bind values to UI Elements
in wdDoInit()
IPrivate<Comp_Name>View.I<ExactOutput>Element input = wdContext.create<BAPI_xxx_Input>Element();
// see if this may demand model instance as parameter
wdContext.node<BAPI_xxx_Input>().addElement( input);
4) In OnAction you just executes the component controller method
wdThis.wdGet<Com_Name>Controller().executeMyBapi();
// executeMyBapi() is the method contains the mentioned try..catch code

Hi,
Do you mean you want to access BAPI in ABAP report?
If yes, then YES we can call,
1.Create a report -> In pattern write your BAPI name.
2. It is like your FM , Read correspoding BAPI documentation
3. Fill required parametes.
4. Test run and if successful , final run it.
And from Outside,
You have to establish a connection and create a wrapper and access using avaialble APIs.

Call BAPI from VBA (access 2007)

Dear Experts
how can i call a BAPI from Visual Basic (in MS Access 2007)
i want to call the BAPI -> BAPI_SALESORDER_CREATEFROMDAT1
please help

Hi, how are you?
Look, it's easy to do a rfc call to SAP.
But, if you look in the Netweaver Developer Studio 7.1, the SAP CONNECTOR is deprecated. So, my recomendation is to convert your RFC's to Web Services, and consume them like that, you won't have any problem with SOAP.

Call report from java with deployment of java web start

I need call report from java,the call function is:execURL ( String pURL )
pURL is a url link to call report from report services .
such as :http://10.20.1.43:8888/reports/rwservlet?destype=cache&desformat=PDF&report=test.rdf&user=scott/tiger@cims
public static void execURL ( String pURL )
String tempstr = new String();
int posIdx = 0;
if ( (System.getProperty("os.name").equals("Windows NT"))||
(System.getProperty("os.name").equals("Windows 2000")) )
posIdx = pURL.indexOf("&");
while ( posIdx > 0 )
tempstr = pURL.substring(0,posIdx)+"^"+pURL.substring(posIdx);
pURL = tempstr;
posIdx = pURL.indexOf("&",posIdx+2);
try
Runtime.getRuntime().exec("cmd /c start "+pURL);
catch (Exception e1) {System.out.println(e1.getMessage()); }
else
try
Runtime.getRuntime().exec("start "+pURL);
catch (Exception e2)
System.out.println(e2.getMessage());
It's run with no problem with deployment of simple jar.
But when i call report with deployment of java web start,it can not.
I think it's java secuity problem,so i add
Permission java.io.FilePermission "c://winnt//system32//cmd.exe", "execute";
in java.policy file in client(windows 20000).However ,it can not too.
Who can help me,Thanks in Advance!

David,
In your code, 'cmd' is invoked as Runtime.getRuntime().exec("cmd /c start "+pURL);
but in your policy file you specify
Permission java.io.FilePermission "c://winnt//system32//cmd.exe", "execute";
Before creating a new process, the security manager checks for FilePermission(cmd,"execute")
if cmd is an absolute path, otherwise it calls checkPermission with
FilePermission("<<ALL FILES>>","execute"). Try specifying
FilePermission("<<ALL FILES>>","execute") in your policy file.
But, I believe using exec, may not be the right solution as it may not work on
other platforms. Also you will have to expect the client m/c to relax security
permission.
Did you consider using java.net.HttpUrlConnection class instead to access the report
service URL?
HTH,
Sathish.

Can anybody send me the sample code...
[email protected]
Thanks for ur help
Pradeep

In PDK you can import RFC modules. For that you have to create a jco connection. The code for calling an simple rfc ....
package com.satyam.callrfc;
import com.sap.mw.jco.JCO;
import com.sapportals.portal.prt.component.*;
public class rfc extends AbstractPortalComponent
     private JCO.Client jcoClient;
// proxy for rfc you already assigned...
     Insert_pgm_PortType insFunc=new Insert_pgm_PortType();
     Zinsert_Pgm_Input ip=new Zinsert_Pgm_Input();
     Zinsert_Pgm_Output op=new Zinsert_Pgm_Output();
    public void doContent(IPortalComponentRequest request, IPortalComponentResponse response)
    this.connect();
     insFunc.messageSpecifier.setJcoClient(jcoClient);
//setting input params
     ip.setAssociate_Id1("44");
     ip.setCourse_Objt1(2);
     ip.setQlty_Content1(5);
     ip.setSeq_Content1(2);
     ip.setTraining_Id1("22");
     try{
//calling rfc
     op=insFunc.zinsert_Pgm(ip);
     }catch(Exception e){}
//display output
          response.write(op.getMessage());
          this.disconnect();
     private void connect() {
               try {
                    jcoClient =
                         JCO.createClient("client","userid","password","EN","application_system","system_no");
                         jcoClient.connect();
               } catch (Exception e) {
                    System.out.println("Error connecting to SAP ::" + e.getMessage());
                    e.printStackTrace();
     private void disconnect() {
               try {
                    jcoClient.disconnect();
               } catch (Exception e) {
                    System.out.println(
                         "Error dis-connecting to SAP ::" + e.getMessage());
                    e.printStackTrace();
