MIXED-DML-OPERATION

Hello Chanchal,

If we perform DML operation on standard/custom object and global objects(User, UserRole, Group, GroupMember, Permission Set, etc...) in same transaction this error will come.
To avoid this error, we should perform DML operation on standard/custom object records in a different transaction.
In general all the apex classes and apex triggers execute synchronously (execute immediately).
if we perform DML operation on standard/custom object records asynchronously (execute in future context), we can avoid MIXED-DML-OPERATION error.

Thanks.
