How to disable all fields in a Dynamics 365 CRM Form?

Background:

Disabling all fields of the Dynamics 365 form may be necessary for certain scenarios, such as when performing data migration or making bulk updates to records.

This prevents users from inadvertently making changes to the data during the process, ensuring that the migrated or updated data is accurate and complete.

Additionally, disabling fields can temporarily prevent users from entering or modifying data until certain conditions are met or specific actions are taken.

Test scenario:

For example,  if a user has submitted a request for approval and it’s currently in the “Pending Approval” status, then they are not allowed to modify any data in the Form.

Test Environment:

Product: Dynamics 365 CRM online

Entity: Account

Event: on load

Logic: If [Status Reason] is [Pending Approval] then disable all fields

Step 1: Write JavaScript

Step 2: Bind On Load Event

Then test it.

Not Recommended Solution

Another solution is that we can also achieve the same functionality through Business Rule.

But we have to manually select all fields and when Add/Remove fields from the Form, we have to modify the Business Rule accordingly.

The scalability is not good, so this is not a good approach.
