Data migration ALE or idocs and bapis

Question

hi ,
thank you guys for the support.
i am into a data migration project.
i need the initial setup for the idocs and bapis.
i dont know anything about these so can u send me the process for the setup and the data migration process too with idocs and bapis.
i didnt understand when they asked me if we can data migrate with a ALE, is that the same as using idocs and bapis or is it a different approach.
u can send me at any inofrmation connected to my eamil addr.
i would really appreciate that.
thank you.

Answer 1

Hi,
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
Application Document Posted.

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.

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 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
Thanks and regards,
