I was trying to open "size of company accounts" report in D365forOps. I got the below error.
I have used https://[Your Dynamics AX URL]/?cmp=USMF&mi=Output:SysCompanySize url.
Initially i thought error is due to SysCompanySize output menu item is in Application Foundation which is referring to SysCompanySize report which is in Application Suite.
So i've created a menu item in Application Suite for the report. Then i tried to open the new menu item, got the same error.
