Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The user does not have write permissions to the Orders table
If the user does not have write permissions to the Orders table, the Patch function may execute without throwing an error but the record will not be created. Options A and B would typically cause an error, not silent failure. Option D (non-delegable data source) does not prevent record creation. Therefore, the most likely cause is insufficient permissions.
