Userinfo elements don't show in Succession adhoc report even after making it reportable in xml
If we make userinfo elements reportable by adding 'reportable=true' in data model xml then the field will be available as reportable in Employee Profile adhoc report NOT in Succession adhoc report.
There is already an open enhancement for making userinfo elements reportable in Succession adhoc report. The fixed date of this enhancement is not released yet.
