Starting Sessions Explicitly: Run Modes

Use

Running a batch input session executes the transactions in the session and enters data into an SAP system.

Usually, the system will run batch input sessions automatically. However, you can also start batch input sessions by hand. You may wish to do this for these and other reasons:

To correct transactions that had errors
To check that the transactions in a session have been generated correctly by running the first several transactions
To start a session on special request (the session would not be started automatically or must be started right away).

Prerequisites

Start the batch input management tool: Select Start of the navigation path System Next navigation step Service Sessions Batch input End of the navigation path . Alternate: Enter transaction SM35. Both paths take you to the session overview of the batch input system. transaction SM35.

Procedure

To start a session, mark the session and choose Process from the tool bar. You can then choose how to run a session and with what logging and display options.

You can start any session in new status that is not locked. With Process/foreground or Display errors only mode, you can also re-start transactions that have the status Incorrect. Sessions with the status Processed cannot be run again.

Run Modes

There are three ways to run a session:

Process/foreground: You can interactively correct transactions that contained errors and step through transactions that have not yet been executed.
Display errors only: This mode is like Process/foreground except that transactions that have not yet been run and which do not contain errors are run non-interactively.

If an error occurs, processing stops and the screen upon which the error occurred is displayed.
Background: Use this mode to schedule a session for immediate processing in the background processing facility.

You receive control of your terminal again as soon as the session has been passed to the background processing system.

Note that your session is automatically released for processing in the background processing system. You need not explicitly release the session for processing.

A completed session is handled in one of three ways:
- The system deletes a session from the queue when it has been successfully completed. You can check on the outcome of the session by displaying the session log file.
- If the KEEP option was set when the session was generated, then the system leaves a session in the queue, even if it was run successfully. The status is changed to Processed.
  
  You cannot run a processed session a second time. You must manually delete it when you no longer need it.
- If a transaction in the session contained an error, the incorrect transaction is aborted. All other transactions are completed. The session remains in the queue and is held in the Errors section of the list. You can correct the session in one of the interactive modes and run it to completion.
  
  A transaction contains an error if it issues a message of type E (error) or type A (abnormal termination). Other messages are ignored and do not affect the execution of a session..
  
  A session also is held in the queue in the Errors list if the session was ended with the /bend OK code. Please see Correcting a Session.
