Existing Security Classes not listed in Shared Services | Assign Access Control

Hi,

I have a few security classes in my classic HFM application which has been added months ago via shared services and which I was able to apply to objects (WDEFs) in workspace.

But I can't see these security classes in the list of the "Assign Access Control" in Shared Services. When I try to add them there the system tells me "Error: This is an EPMA application. The functionality must be done through EPMA."

But we are running this app in classic mode definitely.

When extracting security data out of workspace I can find these security classes in the sec-file. Mysterious.
