165   Improper Error Response for GetDataSetValues

Issue

During testing, a GetDataSetValues requests was executed for a non-existent DataSet. Table 28 indicates that a listOfAccessResult needs to be returned, but the MMS specification indicates that OBJECT-UNDEFINED as a ReadResponseError is the correct response.

Table 23 does not differentiate between AccessResultErrors and error responses.

This impacts several abstract cases.

Proposal

The tables in 14.3.1 need to be clarified for the negative response cases to not refer to Table 23. We need to create another table that discusses the class/code combinations to be returned in the response- case. For the case in point, the response- for Table 28 needs to indicate that the ACSI instance-not-available be translated to an MMS ErrorResponse of class=DEFINITION/code=OBJECT-UNDEFINED.
