Explanation:

In Dynamics 365 Business Central, you can configure pages differently depending on whether you want to make global changes (for all users) or user-specific adjustments:
* Requirement: Display the number of sales orders created for the month to date
* This is a new functionality that does not exist out-of-the-box on the Accounts Receivable Role Center.
* To add a new element (like a KPI or cue) to a role center, you must use the Designer feature.
* Designer lets you modify the role center layout and add fields, tiles, and data elements globally.
* Requirement: Optimize the order entry screen for users
* Users want to rearrange fields, hide unused ones, and change the order of entry.
* This is best achieved with Personalization, which allows users to customize their own page layouts without affecting others.
* Each user can optimize their own order entry process based on how they work.
Why not My Settings or Advanced Settings?
* My Settings is for changing Role Center, Company, Work Date, etc. - not for page or process customization.
* Advanced Settings allows some environment-level adjustments (like features toggle) but not UI customization.
