hi,

1.Open the batch input session session using function module BDC_OPEN_GROUP.

2.For each transaction in the session:

a. Fill the BDCDATA with values for all screens and fields processed in the transaction.

b. Transfer the transaction to the session with BDC_INSERT.

3.Close the batch input session with BDC_CLOSE_GROUP.

4.this is silmilar to the way how u use the other FMS.

CALL FUNCTION ‘BDC_OPEN_GROUP’

EXPORTING

CLIENT = <client>

GROUP = <session name>

HOLDATA = <lock data>

KEEP = <deletion indicator>

USER = <batch user name>

EXCEPTIONS RUNNING

QUEUE_ERROR = 1

CLIENT_INVALID = 2

GROUP_INVALID = 3

CALL FUNCTION ‘BDC_INSERT’

EXPORTING TCODE = <trans code>

TABLES DYNPROTAB = <bdc_table>

EXCEPTIONS

INTERNAL_ERROR = 1

NOT_OPEN = 2

QUEUE_ERROR = 3

TCODE_INVALID = 4

CALL FUNCTION ‘BDC_CLOSE_GROUP’

EXCEPTIONS

NOT_OPEN = 1

QUEUE_ERROR = 2

Note : Close the session after opening it

BDC_OPEN_GROUP.

BDC_INSERT.

BDC_CLOSE_GROUP

Hi,

BDC SESSION METHOD:

-

---

Since Direct Input and Call Transaction methods cannot be used for support projects due to the database availability and networking constraints, SAP suggests to use Session Method for data migration in support projects.

In this method, a session is created in the Application Server. A session has a session memory used to hold the internal table records. We can process the session later whenever database is available with free network traffic.

FUNCTION MODULES USED IN BDC SESSION METHOD:

-

---

1. BDC_OPEN_GROUP - This FM is used to create a session in Appn. Server.

2. BDC_INSERT - This FM is used to insert the internal table records into session memory.

3. BDC_CLOSE_GROUP - This FM is used to save the records in session memory and close it to process later.

Eg. code:

-

---

DATA : BEGIN OF ITAB OCCURS 0,

STR(255),

END OF ITAB.

DATA ITAB1 LIKE KNA1 OCCURS 0 WITH HEADER LINE.

DATA JTAB LIKE BDCDATA OCCURS 0 WITH HEADER LINE.

JTAB-FNAM = FLDNAME.

APPEND JTAB.

ENDFORM.

Save -> Activate -> Execute -> A session is created.

To process the session, GOTO SM35 Tcode.

Navigations to process the session:

SM35 -> Select the session -> click on PROCESS pushbutton from appn. toolbar -> Opens an interface -> Select DISPLAY ERRORS ONLY radiobutton -> Process -> Opens the user-defined screen -> Modify and Insert the records -> Finally opens a message -> Click on Session Overview pushbutton -> Comes back to SM35 screen -> Select the session -> Click on Log Pushbutton from appn. toolbar -> To view the detailed log, select session from here -> Click Analyze Log pushbutton from appn. toolbar -> Opens an interface -> Click on Log Created on...date... tab button -> We can view the detailed log of transaction.

If Background mode is selected, GOTO SM36 Tcode.

SM36 -> Click on Own Jobs pushbutton from appn. toolbar -> Select session from the list -> Click on Job Log pushbutton from appn. toolbar -> Gives you detailed log of background processing.

Hope this helps u,
