This transaction is used to submit a batch job run request. The batch job requested will be queued for execution immediately. Once the desired batch job has been executed, details can be seen via the 'Batch Run History' transaction.
A pdf user guide on Running Batch Jobs is available

The Batch Run Type drop down list contains a list of the valid batch jobs that can be submitted.

You can specify an As At Date for the transaction. The date can either be entered manually or selected from the pop-up calendar by clicking the  icon. The As At Date must be entered in the format DD/MM/YYYY, for example, 01/01/2000.

Clicking the "Last Year End" button is a short cut for populating the AS AT Date field with last year end date.

When entering dates manually, a date guessing routine speeds up the input by taking the user input and assuming the missing month and or year based on the current date as the user leaves the field i.e.

the date today is 30th October 2009

• User enters 15 or 15/ and tabs - field displays 15/10/2009
• User enters 15/9 or 15/9/ and tabs - field displays 15/9/2009
