Out of the box the Change Log facility is only available for selected tables in Epicor 9 and ERP 10.
You can however switch it on for any table you wish to track by enabling it through SQL. After you run the following statement, the ChgLog function will be available in the BPM Designer.

UPDATE [Ice].[zDataTable] SET ChgLogId = 'UD100A', TableLabel = 'UD100A' WHERE [DataTableId] = 'UD100A'
Please note that this method only enables the option in the Workflow Designer, it will not add any display option to the maintenance screen; that would have to be done via customization, only if you need it.
