Question 6 :
Difference between Table-Controls and Step-loops?
Table controls are modified / mproved versions of step loops.
in controls we can do,
scrolling in a perticular field,
resize the table,
can save the settings for future use,
can make selective columns editable,....etc
these things are not possible with step loops.
step loops are controlled by loop-endloop statements.
Question 7 :
Import and Export
ABAP memory is a memory area that all ABAP programs within the same internal session can access using the EXPORT and IMPORT statements. Data within this area remains intact during a whole sequence of program calls. To pass data to a program which you are calling, the data needs to be placed in ABAP memory before the call is made. The internal session of the called program then replaces that of the calling program. The program called can then read from the ABAP memory. If control is then returned to the program which made the initial call, the same process operates in reverse.
