AppBusinessProcess Base Class's CreateFieldsList Function
Your business processor code can pass an array of columns into the base class's CreateFieldsList() function that builds a comma delimited list of fields. Within your business processor code, the comma delimited list of fields can be used within a Transact-SQL data manipulation statement, such as an INSERT statement, to populate the table with data.
For an example, see Creating an Output Table via the CreateOutputTableFromView().
