Question - 14 : - What are screen painter and menu painter?
Answer - 14 : - Screen painter: Screen painter is a tool to design and maintain screen and its elements. It allows user to create GUI screens for the transactions.

Question - 16 : - What is ALV programming in ABAP? When is this grid used in ABAP?
Answer - 16 : - ALV is Application List viewer. Sap provides a set of ALV (ABAP LIST VIEWER) function modules which can be put into use to embellish the output of a report. This set of ALV functions is used to enhance the readability and functionality of any report output. Cases arise in sap when the output of a report contains columns extending more than 255 characters in length. In such cases, this set of ALV functions can help choose selected columns and arrange the different columns from a report output and also save different variants for report display. This is a very efficient tool for dynamically sorting and arranging the columns from a report output. The report output can contain up to 90 columns in the display with the wide array of display options.
