How to make batch session...?

Former Member — Thu, 06 Mar 2008 09:08:28 GMT

Hi shoaib,

Good.

SESSION METHOD

It is one of the BDC techniques for uploading legacy data into SAP

The data is transferring from the internal table to database table

through sessions.

Data along with its action is stored in session.

When the program has finished generating the session, you can run

the session to execute the transaction.

Unless session is processed, the data is not transferred to

database tables.

The following Function Modules are used in the session method.

1. BDC_OPEN_GROUP (Used to create the session)

Import Parameters :

USER - User Name

CLIENT - Client

GROUP - Name of the session

HOLD - The date when you want to process the session

KEEP - ‘X’ – retain session even after processing it

' ' - Delete the session after processing.

2. BDC_INSERT (Data is transferred to session)

Import Parameters :

TCODE - Transaction code

DYNPROTAB – BDCDATA table

3. BDC_CLOSE_GROUP (Used to close a session)

Processing Steps

1. Generate the batch input session using function module

BDC_OPEN_GROUP.

2. The proceed as follows for each transaction that the session

contains:

a. In the BDCDATA structure, enter the value for all screens

and fields that must be processed in the transaction.

b. Use BDC_INSERT to transfer the transaction and the BDCDATA

structure to the session.

3. Close the batch input session with BDC_CLOSE_GROUP.

4. Start to process the generated session in T.Code SM35.

Reward if usefull.

Gokul.

hii!!! the info u have given is really useful thanx....but if i want to put directly into the database which is know as DI( Direct Input) would it be possible to create the batch input session for the DI input metthod

Re: batch input sessions..........

Former Member — Thu, 06 Mar 2008 10:00:34 GMT

Hi Shoaib,

I think thats a confusing stuff you need... Direct Input with Batch???

Direct Input means data will be directly updated in the Database, whereas Batch means you will create a session which can be executed any time.

If you need to create a Batch session and then execute it from the program itself then I have a code which will solve your purpose... Give me your mail ID.. I will send it to you..

Cheers!!
