Mapping resolution field not working

Hi,

I try to map resolution values from a .csv file to the resolution field in RTC.
This is not working.
The defualt mapping generated for the .csv has the following mapping for the resolution:
<attribute sourceId="Resolution"targetId="resolution">
<value sourceId="Fixed" targetId="Fixed"/>
<value sourceId="Incomplete" targetId="Incomplete"/>
<value sourceId="Won't Fix" targetId="Won't Fix"/>
<value sourceId="Duplicate" targetId="Duplicate"/>
<value sourceId="Cannot Reproduce" targetId="Cannot Reproduce"/>
<value sourceId="Build" targetId="Build"/>
<value sourceId="Won't Build" targetId="Won't Build"/>
<value sourceId="No issue" targetId="No issue"/>
</attribute>

I also tried with the following mapping:
<attribute sourceId="Resolution" targetId="com.ibm.team.workitem.attribute.resolution">
<value sourceId="Fixed" targetId="Fixed"/>
<value sourceId="Incomplete" targetId="Incomplete"/>
<value sourceId="Won't Fix" targetId="Won't Fix"/>
<value sourceId="Duplicate" targetId="Duplicate"/>
<value sourceId="Cannot Reproduce" targetId="Cannot Reproduce"/>
<value sourceId="Build" targetId="Build"/>
<value sourceId="Won't Build" targetId="Won't Build"/>
<value sourceId="No issue" targetId="No issue"/>
</attribute>

The resolution field is still empty.
In the source of the project configuration I couldn't find the right id for the resolution field
Pleas help me to solve this issue.

Thanks,

Regards,

Yasar
