Detailed Description

This Service is used to request the next set of QueryFirst or QueryNext response information that is too large to be sent in a single response.

“Too large” in this context means that the Server is not able to return a larger response or that the number of QueryDataSets to return exceeds the maximum number of QueryDataSets to return that was specified by the Client in the original request. The QueryNext shall be submitted on the same session that was used to submit the QueryFirst or QueryNext that is being continued.
