Народ,

Объясните разницу между CALL SCREEN и SET SCREEN. Когда использовать одно, а когда другое? ,
а также LEAVE SCREEN и LEAVE TO SCREEN.

... To start a screen sequence, you have to call its first screen. You can do this either by starting a transaction (the first screen is contained in the transaction definition), or by using the CALL SCREEN statement in an ABAP program. When you call a screen sequence using the CALL SCREENstatement, you nest it within the screen sequence that was already running at the time.
...

Every screen has a static next screen that specifies the next screen to be called after the current one, as long as it is not overwritten dynamically. In the processing logic, that is, a dialog module called by the screen, you can use the SET SCREENstatement to overwrite the statically-defined next screen dynamically:
