1. What are the functions of the dispatcher?
Ans: Measure up to a circulation of transaction load to the work forms.
Management of buffer areas in main memory
Integration of the presentation levels.

Actual Parameters: Parameters which are indicated amid the call of a subroutine with the PERFORM statement.
16. How would you populate data into a various line field?
Ans: To populate data into a multiple line field, an index is added to the field name to demonstrate which line is to be populated by the BDC session (Line index).
