Dashboard Prompt for Manager (Assignment Manager - unsecured)

Summary

Can I add to my existing DB prompts one for the Assignment Manager ?

Content

Hey All,

I have created a headcount dashboard with db prompts like: territory, department, job family etc. and it is working w/o any issues. But if I add the Assingment Manager (unsecured) field to the list and open the filter, I will not see the list of manager names (as stand alone report it is working)....I will get (after ~ 5minutes) the message: "failed to load". Is there a trick how to add this field w/o any issues ?

Thanks for your help !!
