Epicor 9 cannot run some reports after sql permission change

Hello people,

a server i look after is coming up with following error only with domain users, i can run reports okay as domain admin…

this server has always had some sort of issue with sql permissions, now it seems i am unable to access sql views as domain users. The permissions in sql server look okay to me? can any one help?

I also found this error in SQL Server

Date 6/17/2020 3:10:48 AM
