Introduction to ABAP ABAP Exercises Exercise Chapter 7 Introduction to ABAP ABAP Exercises Exercise (Chapter 7): In these exercises you will write programs to help you to understand internal tables with and without header lines. Objectives After completing this exercise, you will be able to: Understand how internal tables work and the differences between internal tables with and without header lines. Estimated time to complete this exercise: 30 minutes Exercises The following exercises provide practice working with the concepts learned in Chapter 7 and Chapter 7a. Exercise 1: Name your program YIN010_XX. The efficiency experts have looked at your programs and have decided that hitting the database repeatedly with the select statement is extremely inefficient (I know, I was shocked too). They suggest you take all the information from the list you created for the last exercise (program YIN009_XX) and first put it into an internal table before writing it out to a report. Create and populate an internal table that will hold the information you would like to select from the database. First create an internal with a header line, next, change your program to use an internal table with a separate work area. Refer to Program YIN010 for solutions to both methods. Exercise 2 Copy your last program as YIN011_XX. Write a program identical in purpose to YIN009_XX but using the internal table you created in YIN010_XX. Also, you should change the ON CHANGE OF statement to an AT…ENDAT statement. The output should be identical. Refer to Program YIN011 for the solution.
