Disable Page & Ribbon Customization
In the RTC client it's possible to prohibit customizations done by users. This can be controlled by user profiles. In the sample I use profile "Project Manager". To assign a profile to a user goto page "user personalisation".
After that close the RTC client and re-open it. After that click on the Dynamics Button (blue button in the top left/corner) on the start page (Home/Role Center) and select menu item "Customize". There we get a list of sub items to customize the page.
Then we change the profile. To change profile settings write "profiles" into the Search box and select page "profiles". Select profile "Project-Manager" and open the card page (Edit Button).
Here set checkbox "Disable Personalization" to true and close the page. After that close the RTC client and re-open the client. Now click again on the Dynamics Button/Customize on the Home Page (Role Center). We get then a reduced list with no customized subitems.
With opportunity to customize you can save filter settings, without you can't.
In Page "Items Factbox "Item Details - Invoicing" the settings button with 2 menu items is visible with default settings.
Without customized opportunity the settings button is invisible.
If you have the problem that a user cannot change page settings (Customizations), then check if the user has assigned a profile with the above settings "Disable Personalization".
