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 tcode 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 and 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.
Step 4. Release BAPI Function
Module:
- 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.
Step 5. Release BAPI object:
- Go back 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.
