A Batch Class can have more than one data table and each data table can have a corresponding separate Properties file. The administrator can make changes in each Properties file for different configurations as needed.

There is a default PO data table po_configuration already configured in the Transact database with the following columns.

• po_line

• po_number

• part_number

• vendor_id

• vendor_name

• quantity

• available_quantity

• unit_price

• item_description

The administrator can also configure an external PO data source as follows:

• On the Tomcat server, add a resource tag in server.xml file for the external data source and the corresponding resource link in the context.xml file.

• Update the Data Source and PO_Table name in the property file.
