AX technical questions

Hi Friends,

can anyone give me a understanding of the below -

  1. How to apply a security key (with scenario :slight_smile: ) ?

  2. What is an Virtual company? Table collections?

  3. Difference between display method on table and a data source?

  4. Why there is a security threat with display and edit method?

Soon reply will be praised.

Defining them at table make them reusable

To enable caching for display methods, place them at table level

To display the value of the display method in a grid, it should be placed in the form data source level
