Emcli set_metric_promotion for aggregate_service

Question

I am trying to promote a metric from generic_service to an aggregate_service. One can do this through the browser interface; is this also supported by emcli? If so, what is the syntax?
Here is an example of a simple attempt, including the command that successfully promotes the metric for an underlying generic_service:
emcli set_metric_promotion -name="DBDEVOEMOSService" -type=generic_service -category=Usage -basedOn=system \
-aggFunction=MAX -promotedMetricKey='Max Aggregate CPU (%)' -column=cpuUtil -metricName=Load -depTargets="hostA;hostB" -mode=CREATE -depTargetType=host
I have tried to use this syntax to promote the metric to an aggregate service:
emcli set_metric_promotion -name="DBDEVOEM" -type=aggregate_service -category=Usage -basedOn=system \
-aggFunction=COPY -promotedMetricKey='Max Aggregate CPU (%)' -column=Usage -metricName=UsageValue \
-depTargets="DEVOEMOSService" -mode=CREATE -depTargetType=generic_service
This returns an error:
Internal Error: The EM CLI system has encountered an internal error. Details have been added to the EM CLI log files.
Unfortunately, there isn't anything in the EM CLI log file, despite the error message saying that there is.
Any tips appreciated.

Thanks but I tried '%' it does not work for promoted metrics.
I tried changing the promoted metric key values via the console ie.
- Click on the Service created
- click on "Monitoring Configuration"
- click "Performance metrics" and edit the metric.
The gui does not allow you to enter values!
You have to select key values that have been collected so far.
However, it would be nice to define the values before we start collecting metric data, and also, be able to define wildcard selections.
I then tried creating the promoted metric via the command line use the verb "set_metric_promotion" and set the key value to '%'.
For example,
emcli set_metric_promotion -name=MY_SERVICE -type=generic_service -category=Performance -basedOn=system -aggFunction=SUM -promotedMetricKey=MyCounter -metricName=MyMetric -column=MyCounter -depTargetType=MyCustomPlugin -depTargetKeyValues=monitor_bld02_08:%;monitor_bld02_09:% -threshold=20;15;GE -mode=CREATE
This executes successfully but when I view the promoted metric via the console, there is an error message
*"ORA-01465: invalid hex number "*
The other problem with this verb is that it doesn't seem to handle composite keys. The documentation only has syntax and examples for single key values.
