What Doesn't Cause Irreversible Changes?

Changes to the sharing model or sharing rules.

In the context of Salesforce, irreversible changes refer to changes that cannot be undone or rolled back. These changes can have significant impacts on your Salesforce instance and its data, so it's essential to be cautious when making them.

To answer the question, we need to identify the actions that do not cause irreversible changes. Here are some examples:

1. Running a report - Reports are read-only, which means that running a report does not make any changes to your data. Therefore, it is a safe action that does not cause irreversible changes.

2. Creating a dashboard - Similar to reports, creating a dashboard does not make any changes to your data. It is a visual representation of the data that is already present in your Salesforce instance.

3. Editing a page layout - Page layouts define the fields and sections that appear on a record detail page. Editing a page layout does not change the data in your Salesforce instance, and it is possible to revert to the previous layout if needed.

4. Creating a new user - Creating a new user does not make any changes to your existing data. It simply adds a new user to your Salesforce instance, and you can deactivate or delete the user if needed.

5. Updating a picklist value - Picklist values are used to provide a list of predefined values for a field. Updating a picklist value does not make any changes to your data, and you can revert to the previous value if needed.

In summary, the actions that do not cause irreversible changes in Salesforce are typically those that do not modify the existing data. Running a report, creating a dashboard, editing a page layout, creating a new user, and updating a picklist value are some examples of such actions.
