Scheduling Function Module in BG

Former Member — Mon, 15 Jun 2009 04:27:18 GMT

Hi,

In one of my conditions I have to schedule a FM in Background, how can I do that, by adding 'IN BACKGROUND MODE AS SEPARATE UNIT' can we achieve this, if yes when will be it scheduled for a run ?

You can use the required FM in a program and then schedule the program for background run.

You cannot directly execute an FM in background...

CALL FUNCTION func STARTING NEW TASK taskname.

CALL FUNCTION

Variant 5 CALL FUNCTION func IN BACKGROUND TASK.

Additions:

1. ... AS SEPARATE UNIT

2. ... DESTINATION dest

3. ... EXPORTING p1 = f1 ... pn = fn

4. ... TABLES p1 = itab1 ... pn = itabn

Effect Flags the function module func to be run asynchronously. It is

not executed at once, but the data passed with EXPORTING or

TABLES is placed in a database table and the next COMMIT WORK

executes it in another work process.

Note This variant applies only as of Release 3.0, so both the

client system and the server system must be Release 3.0 or

higher.

Note qRFC with Outbound Queue

This is an extension of tRFC. The tRFC is serialized using

queues, ensuring that the sequence of LUWs required by teh

application is observed when the calls are sent.

For further information about qRFC, refer to the Serialized

RFC: qRFC With Outbound Queue section of the SAP Library.

Addition 1 ... AS SEPARATE UNIT

Effect Executes the function module in a separate LUW under a new

transaction ID.

It is a zfunction module developed by me.My doubt is in order to set a FM in BG what all the things I need to perform.ie if a set a FM in BG by givving

CALL fUNCTION ZXXXXXXX IN BACKGROUND MODE AS A SEPARATE UNIT will this be enough or do I have to do any thing more. Any inputs ?
