To maintain an orderly sequence of document numbers for easy reference of transactions, certain companies enforce strict controls to prevent users from arbitrarily changing the document numbers. This is achieved through user access rights settings, which restrict unauthorized modifications to document numbers. 

By implementing this control, companies ensure the integrity and coherence of their transaction records, facilitating efficient retrieval and management of data

1. Maintenance > User Role > Select the user roles you would like to control 

2. Permission > Transactions > Change Document Number. We choose 1 for example, let’s say ‘Purchase Requisition’ > Tick this setting

3. In Purchase Requisition transaction > The Document Number is  PR2111/005

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

4.  Untick the setting ‘Change Doc Number’ for Purchase Requisitions

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