Currently, it is necessary to use a basic DSN connection string (with the 32-bit ODBC Greenplum driver) and a database type of "Progress" in order to add a Greenplum data source to the DSP framework.
Additionally, there is no Greenplum connection type that is available in Collect which would allow a user to build Cranport packages for a Greenplum data source (The "Progress" connection type is not compatible). This necessitates using Assemble and manually adjusting Assemble's "Progress" datatype conversions.
Thank you for considering this request.
