Programming a BAPI consists of some tasks like:

u2022 Defining BAPI Data structures ( using SE11 )

u2022 Creating BAPI Function Modules (For each method)

u2022 Defining BAPI Methods in the BOR

u2022 Generate and release

1. Defining BAPI Data structures: This is the basic step followed while creating BAPIs. All the relevant structures that are required for BAPI have to be created using T-Code SE11. The structures can be created for Import/Tables parameters.

2. Creating BAPI Function Modules: We must create new function group for each BAPI. If the BAPIs are related then the same can be grouped under the same FUNCTION GROUP to enable the sharing of global data amongst the related BAPIs.

3. Defining BAPI Methods in the BOR: When creating a new object type in BOR (Business Object Repository), there can be two possibilities. Either it is created as a subtype of an existing business object or it is created as a new business object from scratch. Create a business object using the T-Code SWO1. The business object gets created with the standard interface that contains an Interface IFSAP, an Attribute ObjectType, and two methods namely ExistenceCheck and Display. All these cannot be changed. You can add a method to the business object. For this, we will choose from the menu path, Utillities -> API methods -> Add method. To use the business object Object type status has to be set to Implemented.

4. Generate and Release: Go to SE37 and release the API enabled Function module. In the Object created in the BOR, set the status of Object Type Component to Released.

You can then display the BAPI in the BAPI Explorer. Invoke the same using the T-code BAPI.

Example Code

U need to give the step_nr, item_nr, cond_count and cond_type so the correct conditon will be updated. If no condition exists for the given parameters, a new condition will be created.

U can find these parameters for a particular condition type in table KONV.

Bdc to Bapi

The steps to be followed are :

1. Find out the relevant BAPI (BAPI_SALESORDER_CHANGE for VA02).

for VA01 use BAPI_SALESORDER_CREATEFROMDAT2

2. Create a Z program and call the BAPi (same as a Funtion module call).

2. Now, if you see this BAPi, it has

-> Importing structures.

eg: SALESDOCUMENT: this will take the Sales order header data as input.

-> Tables parameters:

eg: ORDER_ITEM_IN: this will take the line item data as input.

Note :

Only specify fields that should be changed

Select these fields by entering an X in the checkboxes

Enter a U in the UPDATEFLAG field

Always specify key fields when changing the data, including in the checkboxes

The configuration is an exception here. If this needs to be changed, you need to complete it again fully.

Maintain quantities and dates in the schedule line data

Possible UPDATEFLAGS:

U = change

D = delete

I = add

Example

1. Delete the whole order

2. Delete order items

3. Change the order

4. Change the configuration

Notes

1. Minimum entry:

You must enter the order number in the SALESDOCUMENT structure.

You must always enter key fields for changes.

You must always specify the update indicator in the ORDER_HEADER_INX.

2. Commit control:

The BAPI does not run a database Commit, which means that the application must trigger the Commit so that the changes are read to the database. To do this, use the BAPI_TRANSACTION_COMMIT BAPI.

For further details... refer to the Function Module documentation for the BAPi.

Bapi to VB(Visual Basic)

Long back I had used the following flow structure to acheive the same.

Report -> SM59 RFC destination -> COM4ABAP -> VB.exe

my report uses the rfc destination to create a COM session with com4abap. com4abap calls the vb.exe and manages the flow of data between sap and vb exe.

You need to have com4abap.exe

If com4abap is installed you will find it in sapgui installatin directory , C:Program FilesSAPpcsapguiRFCSDKcom4abap.

else refer OSS note 419822 for installation of com4abap

after making the settings in com4abap to point to the vb program and setting up rfc destination in sm59 to point to com4abap session , you can use the following function modules to call the vb code.

for setting up com4abap and rfc destination please refer to the documentation for com4abap.

Invoke NEW DCOM session

call function 'BEGIN_COM_SESSION'

exporting

service_dest = service_dest "(this will be a RFC destination created in SM59)

importing

worker_dest = worker_dest

exceptions

connect_to_dcom_service_failed = 1

connect_to_dcom_worker_failed = 2

others = 3.

call function 'create_com_instance' destination worker_dest

exporting

clsid = g_c_clsid

typelib = g_c_typelib

importing

instid = g_f_oid

exceptions

communication_failure = 1 message g_f_msg

system_failure = 2 message g_f_msg

invalid_instance_id = 3

others = 4.

call function 'com_invoke' destination worker_dest

exporting

%instid = g_f_oid

%method = 'UpdatePDF'

sntemp = g_v_const_filent

snsysid = sy-sysid

snflag = 'N'

tables

rssaptable = g_t_pdfdetail1

%return = g_t_pdfdetail1 "t_test

exceptions

communication_failure = 1 message g_f_msg

system_failure = 2 message g_f_msg

invalid_instance_id = 3

others = 4.

then close the com session , using

FM delete_com_instance

FM END_COM_SESSION

BAPI stands for Business Application Programming Interface.

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 don’t 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.

or

1. Go to transaction SWO1. Enter object interface type. Eg.(ZOBJ)

2.Change the object type release status to implemented and save the object type.

3. Using Z_BAPI (created from SE37) create an API method in the new object type.

4. In the created BOR object ZOBJ, create a new method using the function module template.

5. Input as function module name Z_BAPI.

6.Check the Instance Independent checkbox and click on the next button to continue.

7. On the parameters screen validate whether all the needed parameters are present and click on next.

8. Click Yes on the Extend program dialog to generate the call in the new method.

9. Change the release status of the object type to “To released”

10. Change also the release status of the method type to “To released”

11. Double-click on the new method ZBAPI and go to the tab ABAP and change the ABAP type from Function Module to API method.

12. Finally click on Generate button to generate the object interface and save the object type.

Hope it somehow gets you an idea how to implement a BAPI based on a FM created in SE37.
