Hi CRM Folks,
While we were working on Dynamics 365 On Premise 8.2 Version, we found this issue which is occurring on create of custom entity records in one of our environments. However we see the same customizations in both the environments.
After investigation by observing event logs, we found that this issue is caused due to some security issue. Later we identified that the plugins steps registered on create were running security context of user.
We were able to resolve this issue with the help of impersonation to run Plugins with higher privileges. For detailed info, see below reference.
Cheers,
PMDY
