Tip: Interface patterns give you an opportunity to explore different interface designs. Be sure to check out How to Adapt a Pattern for Your Application.
In an inline editable grid, track the employees that are added for further processing in the next process steps.
This design pattern is not recommended for offline interfaces because reflecting immediate changes in an interface based on user interaction requires a connection to the server.
Also track the ids of items that are deleted for use in the Delete from Data Store Entities smart service after the user submits the form.
