In CRM 2013 / 2015, new auto save feature has been introduced by MS CRM. This feature will save you changes without pressing save button, thus you don’t need ‘Save’ and ‘Save and Close’ buttons. But many users don’t like this, they want those buttons on form. To do this you need to off this auto save feature from MS CRM’s system setting. by doing this these buttons will appear on each form.
Enjoy !! 🙂
