how to submit workflow background process from backend

Workflow is an important part of Oracle Ebiz Applications In this post, we will check out what is Workflow Background Engine, How to run Workflow Background Process from Unix, How to run Workflow Background Process using SQLPLUS, how to submit workflow background process from backend

What is Workflow Background Engine

• The Background Engine is a PLSQL Procedure that checks for and executes any deferred or timed out activities in the workflow system. The arguments of the procedure at the time invoking the procedure determine what all be executed by the Workflow Background process.
• If new activities are deferred or timed out after the current Background Engine is started, the procedure will check one more time for any new activities to execute before terminating. When all matching activities have been completed, the procedure comes to an end.
• Workflow Background Engine can be run as a Concurrent program or as a package command on the SQLPLUS command.
• Let’s check How to run Workflow Background Process using SQLPLUS, how to submit the workflow background process from backend in coming headings

How to run Workflow Background Process from Unix

There is one SQL script placed in $APPL_TOP which can be used to run How to run Workflow Background Process from Unix

$FND_TOP/Admin/Sql/wfbkg.sql

The script will be like

cat workflow_background.sh
sqlplus apps/<apps pass> << EOF
@$FND_TOP/Admin/Sql/wfbkg.sql
exit
EOF

How to run Workflow Background Process from SQL*Plus

We can connect to the apps user and fire the below command

BEGIN
wf_engine.background (itemtype=>NULL ,
process_deferred=>TRUE ,
minthreshold=>NULL ,
maxthreshold=>NULL ,
process_timeout=>FALSE ,
process_stuck=>FALSE);
END;
/
Or
exec wf_engine.background;

how to schedule periodic workflow background process concurrent program from backend

Here is the script which can be used for this purpose for scheduling periodic Workfow background process concurrent Program at 16:40 starting at 20 Feb with daily frequency

DECLARE

BEGIN
–Initialize the session with appropirate values

–Submit the Request
v_request_id := FND_request.submit_request(application => ‘FND’,
program => ‘FNDWFBG’,
description => NULL,
