Hi

What is your Query? BAPI or ALE?

ALE is used to exchange data between intercompany application servers

where as BAPI is used as an interface between R3 systems or R3 and external systems

see the doc of both

Application Linking and Enabling (ALE)

In this document you will learn the step-by-step procedure to setup the ALE system and go through a transaction between two clients

For our purpose we have two clients

namely Client 100 and Client 200.

System name is SAPKDC (FOR BOTH 100 AND 200 CLIENTS).

Distribution of Material Master Data Between two Systems

1) SETUP LOGICAL SYSTEM: (Note: Do Not Create This Step)

To do this follow the following steps

Execute SALE Transaction Code

On The Screen Click on Sending and Receiving Systems.

Then Click on Logical Systems.

Then Click Defining Logical Systems.

Click New Entries Button

(E.g. (LG100 sending system)

(LG200 receiving system))

Enter two logical system names and their description.

Save

Comeback to SALE Transaction Code screen.

2) Now you have to allocate the created logical systems to respective clients.( Note: Do Not Create This Step)

LG100 assign to client 100

LG200 assign to client 200

To do this, do the following.

Click Assigning Client to Logical System.

Ignore the message that comes up on the screen.

Select client 100

Click details button on the toolbar icon or press F2.

In the logical system box, enter LG100.

Click on the save Icon

Click the back button.

Now select client 200.

Click details icon or press f2.

In logical Systems box, enter LG200.

Save

Back.

Comeback to SALE Transaction Code screen.

3) Maintain RFC Destination: (TR.CODE:SM59)

(Note: Do Not Create This Step)

Click Create Button on the Screen

On the Screen Maintain RFC Destination i.e LG200.

Enter LG200 in RFC destination box.

Connection type is 3

Give a description for the RFC destination.

Maintain Technical Settings on Details on Technical Settings tab

Target Host as : SAPKDC (NOTE: Save it as a Host Name)

Maintain Logon Details on Logon/Security tab.

Language: EN.

User: MMUSER200 (This is the logon for dist.)

Client : 200

Password: MM1234.

Save.

Click on create to do the above process for Client 200 in

The client 200 system.

4) Maintain Distribution Model.(BD64). (ABAPer role starts here)

Execute Maintain distribution model directly for

creating the model.

Click on change mode button on App tool bar of the Screen.

Create Model View pushbutton on App tool bar of the Screen.

A pop screen will appear in which you specify

Short text as Distribution for MM Data.

Enter Technical Name as LGMODEL.

Select Model View and Click on Add Message Type Pushbutton on App toolbar of the Screen.

A popup screen will appear in which you specify

Model View as LGMODEL.

Sender as LG100.

Receiver as LG200.

Again Click on Add Message Type Pushbutton on App toolbar of the Screen.

A popup screen will appear in which you specify

Model View as LGMODEL.

Sender as LG200.

Receiver as LG100.

SAVE.

On the same screen goto Menubar and select Environment.

And then select Generate Partner Profiles , then execute it.

On the Screen specify the Logical System as LG200.

Then execute the screen.

Click back.

Again On the same screen goto Menubar and select EDIT.

Again select Model View and then select Distribute.

****LOGIN to client 200.

Execute Tr.code BD64 and again On the same screen goto Menubar and select Environment.

And then select Generate Partner Profiles , then execute it.

On the Screen specify the Model View as LGMODEL

And Specify the Logical System as LG100.

Then execute the screen.

Click back.

*******Switch back to client 100 Session.

5) Create Material using MM03 Tr.Code.

Enter the material name as LGMATERIAL

Industry sector as Mechanical Engineering

Material Type as Finished Products.

And then Click on Data Pushbutton on the App tool bar.

Select views.

In the select views box for materials check basic data 1 AND 2.

Click enter icon.

In the next screen that you get

Give the text of the material as NEW MATERIAL.

Base unit of measure as KG.

Gross Weight as 200.

Net Weight as 100.

Weight Unit as KG.

In the description area language (E) and material description.

Click Save.

Now I Created a Material in Client 100 , I want to transfer this data to Client 200.

6) Execute BD10 to transfer the material in which you specify

the material as LGMATERIAL and

message type as MATMAS (client100).

Then a Screen will be displayed in which it shows that

1 Master Idoc Generated .. Enter

1 Communication Idoc Generated..Enter.

*******LOGIN to Client 200.

7) Execute BD11 to get the material in which you specify

the material as LGMATERIAL and

message type as MATMAS (client200).

😎 Execute Tr.code MM03 and give the material as LGMATERIAL

and see that the material is displayed as it was in Client 100.

If not follow these steps.

9) Execute Tr.code WE19( for rectification of errors in client200).

Specify the Existing Idoc Number and Executes it .

A Screen is displayed in which you specify the corresponding Function Module as INPUT_IDOC_MATMAS01 and execute it.

10) Execute Tr.code MM03 and give the material as LGMATERIAL

and see that the material is displayed as it was in Client 100.

Now the Material is correctly displayed in Client 200.

11) Monitoring of IDOCS.

Transaction Codes:

IDOC Display of Status: WE 05.

IDOC Date and Time: WE07.

Outbound:

Step 1. Application document is created when transaction is saved.

2. Message control is invoked.

3. Messages are processed by system.

4. Messages are Edited (if desired).

5. Output (ALE / EDI) is checked

6. Validate against Message control record from Partner Profile

7. Application Document is saved.

8. Entry NAST table is created for every selected output program

along with Medium & Timing.

9. Check for Process Immediately .

If (yes)

Determine Processing Program from TNAPR Table.

ELSE

Execute RSNASTED Program.

10. Read Partner Profile to determine Process Code.

11. Process Code points to the Function Module & Invoked.

12. IDoc is generated.

13. Check for ALE Request.

if (Yes)

Perform Filters, Conversions, Version Changes etc.

Else.

IDoc is stored in DATABASE.

INBOUND:

Step 1. EDI Subsystem creates an IDoc file from EDI Messages

2. Subsystem calls Functional Module EDI_DATA_INCOMING from startRFC program.

3. Data in Control Record is validate against the Partner Profile.

4. IDoc is generated in Database and syntax check is carried out.

5. IDoc file is deleted once file read.

6. Event PROCESSSTATE REACHED is triggered in Idoc Object Workflow.

7. Check for Process Immediately.

If NO

Execute RBDAPP01 Program

Else

Read Process Code from Partner Profile

Process Code Points to Function Module

BAPI

what is BAPI?

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.

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 Files\SAPpc\sapgui\RFCSDK\com4abap.

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
