"As a beginner in Dynamics F&O, I’d like to understand the purpose of using the 'element' keyword instead of 'this' or 'formrun.' In what scenarios is it best to use 'element' over 'this'?"

    Element and FormRun is coupled with forms. I haven't found a F&O specific page, but this AX2012 version briefly touches on it: Using Variables with Forms | Microsoft Learn
    You should use element when you are working with forms. A good tip is to try to find an example pattern in the standard application and stick to it.
     
    For the rest, there is this X++ syntax - Finance & Operations | Dynamics 365 | Microsoft Learn article on Microsoft Learn.

    Hi Dinesh,
     
    1. element: references the FormRun so if we place our code outside the datasource on the entire form, both element and this references to the FormRun() object.
    2. this: If your X++ code is placed inside a form datasource then it will reference the datasource whereas element in this case will still reference to the FormRun(). 
     
     
    References:
     
    Hope this helps.
