Fun as always working with Dynamics 365 🙂
Kept getting this typical error on creation of a new record which had some look up values.
“The requested record was not found or you do not have sufficient permissions to view it.”
After spending sometime, discovered that there was a JavaScript file loading some look up values to filter records (pre populated GUID in JavaScript) and that GUID value did not exist in that environment.
After updating that GUID, it started working 🙂
