SQL4028 - The query contains a distributed table

SQL4028
Message Text: The query contains a distributed table
Cause Text: A distributed table was specified in the query which may cause the query to be processed in multiple steps. If the query is processed in multiple steps, additional messages will detail the implementation for each step. Access plan implementation information for each step is not available because access plans are not saved for the individual steps.

Debug messages detailing the implementation of each step can be found in the joblog if the query is run in debug mode using the STRDBG CL command.
Recovery Text: For more information about how a distributed table can influence the query implementation refer to the Distributed Database Programming information.
