A Business Data Catalog Entity’s Method for a database needs two properties to be defined, RDBCommandType and RDBCommandText.

Possible values for the Command Type are Text, Stored Procedure and TableDirect.

As we know each BDC property has its name and type. So, name for the Command Type property should be RDBCommandType and its type is System.Data.CommandType.

If you use BDC Meta Man to generate you Application Definition File, then this property is added to file automatically, based on what you use a Stored Procedure, or table/Query.
