For example, a Developer tool user creates a mapping with a Rank transformation where the Rank and Group By ports are specified through parameters. The parameters that represent the Rank and Group By ports are assigned the same value. A Rank transformation cannot use the same port for the Rank port and the Group By port, so the mapping is not valid after compilation. Metadata Manager does not load metadata for an application which contains a mapping that is not valid.

If the resource contains one application with a mapping that is not valid, Metadata Manager fails the metadata load.

If the resource contains multiple applications, Metadata Manager does not load any application which contains a mapping that is not valid. Metadata Manager logs an error in the load log for each application that it cannot load. Metadata Manager continues to load the other applications in the resource.
