Why This table"com.ibm.team.git.GitCommitDescriptor" records do not exist even one

I am trying to create a report.
The development has been using BIRT.
In RTC5.0.2 There is a "com.ibm.team.git.GitCommitDescriptor" in the DB of the table.
Link has been Git committed to the RTC, it was speculated that has been recorded.

"Git link" in a change set (remote) will have a table that seems to have been stored. But, 1 does not have a record.

Can not I view the work items link for Git , it will not be the configuration management.
Please tell me the cause.
Also, please tell me the table that you can get the same information.


Thanks Regard
