Render2 renders a processed report associated with the report execution identified in the ExecutionInfo2 header. If no session snapshot exists, this method will execute the report (if all credential and parameter requirements are met), resulting in a new session snapshot being created. If the report needs to be reprocessed because non-query parameter values have changed, the snapshot will be reprocessed.

If the execution options are set to cache or execution snapshot, the call to Render2 may use an existing snapshot.

If the report is set to cache and the supplied parameter values and credentials match, the cached copy of the snapshot may be loaded instead of actually processing the report.

If credential and parameter requirements are not met, this method will return an error.

Subsequent calls to Render2 can be used to fetch additional pages of the report if the rendering extension supports specifying multiple pages.

A limitation of the Render method is that the output cannot be streamed, so the entire file must be in-memory.

Please see 실행 상태 식별 for a discussion of the execution life cycle, which includes a description of the steps necessary to load and render a report.
