Before we get into what goes into cloud security, we need to have a basic understanding of what a cloud deployment means to your IT environment. We’ll talk about the types of clouds and the layers of cloud computing that you can use, then finish with a discussion of what an SAP system can look like in a cloud environment and some of the threats that the system can face.
This chapter is about master data creation using a screen program. We are starting screen programming for managing master data, but at this level we are using a simple screen design and very basic screen elements. We will design screens for site master data, site assignment to a user, and article master data. While in the development process, you will get an understanding of the different screen elements and the flow logic of screens. You will experience the creation and use of a selection screen and learn about screen validation by applying different input checks that restrict use to ensure the correct values are entered in screen fields. Details on dealing with the database for reading, creating, and modifying records and how to create transaction codes are included. At the end of this chapter we will go through the process of attaching a search help to any field on general or selection screens.
