pack_data

The pack_data table holds the field name and value of every assigned field in every outstanding step on the system.

When a work item is sent out to a queue, field data is copied from the case_data table to the pack_data table. The client uses the field values in the pack_data table to fill out the form correctly. When the form is kept any changed fields are updated in the pack_data table. When a work item is released, field data is moved from the pack_data table to the case_data table.
