161 SAP ABAP Questions And Answers
42⟩ Different types of LUWs. What are they?
Two types of LUW are:
1) DB LUW - A database LUW is the mechanism used by the database to ensure that its data is always consistent. A database LUW is an inseparable sequence of database operations that ends with a database commit. The database LUW is either fully executed by the database system or not at all. Once a database LUW has been successfully executed, the database will be in a consistent state. If an error occurs within a database LUW, all of the database changes since the beginning of the database LUW are reversed. This leaves the database in the state it had before the transaction started.
2) SAP LUW - A logical unit consisting of dialog steps, whose changes are written to the database in a single database LUW is called an SAP LUW. Unlike a database LUW, an SAP LUW can span several dialog steps, and be executed using a series of different work processes.
43⟩ What is LUW?
Logical Unit of Work

47⟩ What are the difference between call screen and leave screen?
Call Screen: Calling a single screen is a special case of embedding a screen sequence. If you want to prevent the called screen from covering the current screen completely, you can use the CALL SCREEN statement with the STARTING AT and ENDING AT
CALL SCREEN 1000.
CALL SCREEN 1000 STARTING AT 10 10 ENDING AT 20 20.
LEAVE SCREEN statement ends the current screen and calls the subsequent screen.
LEAVE SCREEN.
LEAVE TO SCREEN 2000.
48⟩ If internal table used in for all entries in empty then what happens?
No, records will be displayed.
49⟩ If I forgot some command in SAP Script e.g. suppress zero display - How to do find it?
Suppressing of entire screens is possible with this command. This command allows us to perform screen processing “in the background”. Suppressing screens is useful when we are branching to list-mode from a transaction dialog step.

58⟩ What are the differences between SAP memory and ABAP memory?
ABAP Memory is a memory area in the internal session (roll area) of an ABAP program. Data within this area is retained within a sequence of program calls, allowing you to pass data between programs that call one another. It is also possible to pass data between sessions using SAP Memory.
SAP Memory is a memory area to which all sessions within a SAPgui have access. You can use SAP memory either to pass data from one program to another within a session (as with ABAP memory) or to pass data from one session to another.
59⟩ What are differences between At selection-screen and At selection-screen output?
AT SELECTION-SCREEN event is triggered in the PAI of the selection screen once the ABAP runtime environment has passed all of the input data from the selection screen to the ABAP program.
AT SELECTION-SCREEN OUTPUT - This event block allows you to modify the selection screen directly before it is displayed.
60⟩ What is get cursor field?
GET CURSOR statement transfers the name of the screen element on which the cursor is positioned during a user action into the variable <f>.
GET CURSOR FIELD <f> [OFFSET <off>] [LINE <lin>] [VALUE <val>] LENGTH <len>].
