How to decode status_code in FND_CONC_REQ_SUMMARY_V?

Hello,

We run nightly production jobs for four operating units in four special "corporate" user accounts.  I'm writing an SQL query to report errors or warnings found in any of the "corporate" user accounts.  I'm running the query against FND_CONC_REQ_SUMMARY_V.   Can anyone assist with the decode of the values in the STATUS_CODE field;  values are C, E, and G?

I think 'C' means normal.

Thanks.
