The Configure Table Auditing window allows you to choose which columns you want to audit from the selected table.
Specify how many rows of data to include in the audit stream
Specify how many rows of data you want to capture for each audited column. A single DML transaction can contain multiple rows of data, depending on the modification performed. Consider selecting a low number of rows until you can identify exactly which data you need to audit from the transaction.
Select the columns to audit
Choose whether you want to Audit All Columns or Audit Selected Columns. You can select any column that does not contain BLOB data.
