# 5. Known Issues

This section summarizes known issues and limitations of the current release of the Record and Replay Service. Please see the Release Notes supplied with the product for additional information.

## 5.1. Ability to create topics

The service does not yet have the ability to implicitly create topics for the data it replays. To bypass this limitation, the `DCPSTopic` built-in topic can be included in the recording (and replaying) of data.

The following interest-expression should be used:

> `__BUILT-IN PARTITION__.DCPSTopic`

To ensure that a topic is re-created at replay before any data belonging to that topic gets replayed, the `DCPSTopic` expression should be the first interest-expression that is added to a particular storage using the add record/replay commands.
