If this input parameter gets its value from an output parameter, this is the source parameter. If the value of this BPParameter is a constant, the Reference property has no meaning.

When setting the Reference of the target BPParameter, ensure that there are no instances of BPIterationParam created from that target BPParameter. Note that when a Component is added to a BusinessProcess, one BPIteration is added automatically, together with BPIterationParams for all of the component???s parameters. Delete them in your code before setting the Reference. Failure to do so results in an error when attempting to view or run the test.
