We've got RTC 5.0.1, and the data collection job Work Items fails every night.  The Build, SCM, APT, Repository, and Common jobs all succeed.

In the logs, we're seeing this error

[26/03/15 0:08:08:301 CDT] 000001c8 SystemErr     R 2015/03/26 00:08:08:301 CDT [ERROR] VegaDataServices - The following com.ibm.team.reports.service.rest.exceptions.InternalRepositoryException exception was thrown while processing the url: https://alm.wcb.mb.ca/ccm/rpt/repository/workitem?fields=workitem/workItem[projectArea/archived=false]/(itemHistory/(type/id|foundIn/itemId|projectArea/itemId|teamArea/itemId|owner/uniqueId|target/itemId|resolver/uniqueId|resolution/(workflow/id|id)|category/itemId|state/(workflow/id|id|group)|severity/id|priority/id|creator/uniqueId|modifiedBy/itemId|id|itemId|uniqueId|@href|contextId|summary|tags|creationDate|modified|resolutionDate|dueDate|duration|correctedEstimate|timeSpent|stateId|predecessor|dayModified|commentCount|subscriberCount|integerComplexity|activationDate)|projectArea/archived)&modifiedsince=2015-02-20T00:00:00.000-0600&size=10&pos=80&id=_Bd_rQNN2EeSn0vZVuNjMVw

and it also says

Caused by:  [CRJAZ1316E The user "Jazz-SQL-DW-Admin" does not have permission to read items that have the Category access type.]
 <com.ibm.team.reports.service.rest.exceptions.InternalRepositoryException: Internal Repository Error>com.ibm.team.reports.service.rest.exceptions.InternalRepositoryException: Internal Repository Error

I'm going to try putting the DW Admin user into the Jazz Admins group, but I don't know if that's the right fix.  It might succeed through brute force, but I would prefer a more elegant solution if there is one.
