# Processing Messages and Pause Reasons

> The refusals before a run, the pause reasons of a background run, and the error codes a record can carry, with whether it may be retried.

> **Draft brief for authors.** Three tables: refusals before a run · pause reasons · record error codes (with "retryable or not").

**Page type:** Reference · **Audience:** Business user, Administrator
