try updating the custom property schema. To do this:
open the custom property editor
right click on an empty part of the toolbar and select customize.
select the commands tab.
scroll down through the list of commands until you see update report schemas.
drag the update report schemas item up to an empty space on the toolbar
close the customize dialog box.
click the new icon you just created on the toolbar to update the schema.
Not sure if this is your fix or not but it has fixed some previous problems.
Hi I already tried that but no joy.
The custom properties are availalble when creating reports but the Grouping drop down has shrunk and does not show any custom properties.
We had same issue - seemed to happen after I restarted the server which hosts SQLServer. Followed your suggestion and I'm now able to see custom properties in the Grouping drop down list in Orion web.
Question: Do I need to run this "update report schemas" each time we restart the SQL backend ?
