Hi Shariq, 

Just want to know if you had any luck with this situation as I am also experiencing the same issue. Scheduled job used to be run as one of my colleagues who left the organization, so we changed the run as other user, who has the same permission as my previous colleague, since then we started experiencing this issue. 

Scheduled job gets executed, however it doesn't update the records. But when I run the same code in background script, it works fine. Not sure, what's the issue is. Any help in this regard will be much appreciated! 

Thank you,

Chiranjeevi
