Hi,
The thing is that PDW uses slightly different system views and procedures than SQL Server and also architecturally it is a bit more complicated (replicated versus distributed tables, distribution keys for distributed tables, tables can be physically stored as row store or column store etc.). As a result I am able to reverse engineer from PDW but none of mentioned specifics is reversed (as a result plain tables are reversed), publishing from the model into PDW does not work at all at the moment.
