When a customer receives a permission error when opening costing periods, what configuration is needed?

The correct choice involves creating Data Access on the Cost Accountant role for the appropriate cost organization. This configuration is essential because access permissions dictate which users can perform specific actions within the Oracle Cloud Cost Management module.

When a customer encounters a permission error while trying to open costing periods, it typically indicates that the user does not have the necessary access rights to interact with the data associated with those periods. By configuring Data Access for the Cost Accountant role, you ensure that the user has the proper permissions tied to the specific cost organization they need to work with. This means that they will be able to perform their tasks without running into permission-related issues.

In contrast, modifying user roles in the administration panel may not directly address the specific access needed for the cost organization in question. Similarly, assigning a new user to the cost organization does not solve the existing user's access issue and could introduce unnecessary complexity. Rotating user permissions weekly is also not a practical solution for resolving immediate permission errors and does not contribute to a stable and secure access configuration.

Thus, creating specific Data Access configurations tailored to the user's role and responsibilities presents the most effective solution for rectifying permission errors when opening costing periods.
