The following two sql statements cause the error:

CREATE INDEX UI_u2297_sourcedocument ON dbo.DocVersion (u2297_sourcedocument) ON Index
CREATE INDEX UI_u2988_applicationname ON dbo.Generic (u2988_applicationname) ON Index

The incorrect syntax is due to the "ON Index" part of the sql statement. The customer had created a filegroup in MS SQL called "Index" to be used for their indexes.
