Some companies are strict to have document in consistently for audit purpose.

To prevent user from randomly changing the document number, user access right is set.

1. Go to Maintenance > User Roles

2. Go to Users to set the role to user.

3. Go to Permissions > Transactions

4. Tick the documents you would like to Change Doc Number. For example, Purchase Requisition

The Document Number is  PR2111/005

User is able to change the Document Number to PR2111/006

5. Untick the Purchase Requisitions

This block user from changing the doc number and disrupt the order of doc number.
