Usage

The ongoing operation covers only part of a screen that has multiple controls, and:

File Upload: The file upload dialog contains multiple upload operations. The user must be able to cancel each operation. Since the operation is related only to one row and not to the full app, there is no need to block the whole screen. The user still needs to interact with the system, in this case to select the next file to be uploaded.

Table Rows: Each row in the table has an action related to the table item. Clicking the Run button in a specific row changes status of the current item. The user is still able to work on the other items or cancel the current operation.
Since each SAPUI5 control provides a busy state by default, you could also set the busy state at row level. In this case, however, there would be no option to cancel the operation.

The operation takes less than one second.
You need to block the screen because the user is not supposed to start another activity. In this case, use the busy dialog.
