This article describes the issue when Web Help Desk allows Reports to be grouped and set the Tech Groups the access to run or view these reports, WHD is unable to delete the access permission when a WHD Admin tries to delete the Tech Group(s). You also get the following error:
"Problem deleting the Tech Group: com.webobjects.eoaccess.EOGeneralAdaptorException: EvaluateExpression failed: : Next exception:SQL State:23000 -- error code: 547 -- msg: The DELETE statement conflicted with the REFERENCE constraint "REPORT_GROUP_TECH_GROUP_techGroup_FK". The conflict occurred in database "whd", table "dbo.REPORT_GROUP_TECH_GROUP", column 'TECH_GROUP_ID'."
This is caused when a Tech Group is assigned to a Report Group/s.
