Advertisement SAP ABAP dialog programming can be a blurry term denoting one or another thing for different specialists. However, in this tutorial, we will stick to the general approach and will consider SAP ABAP dialog programming as programming involving dialog objects, such as classic SAP screens (Dynpros), selection screens, transactions, GUI statuses and all controls of SAP GUI Control Framework.

Let us consider two main dialog objects in ABAP: classic screen and selection screen. Advertisement Classic Screen Classic screen or Dynpro is the thing you will meet most often in. It can comprise of multiple smaller objects and controls inside. Here is the schematic picture of a typical SAP ABAP screen. SAP ABAP Screen The above screen is the standard screen from CR03 transaction. However, users can freely create custom screens too. Every screen, besides graphical representation, has its internal number and programmatic entity. It can be reviewed in transaction ( SE80) by ticking target program hierarchy and expanding screens tree. SAP ABAP Screen in Program Hierarchy Each screen is a programmatic object which can be called by the ABAP statement CALL SCREEN like this: CALL SCREEN dynnr. Where dynnr is a Dynpro number. Advertisement It is worth saying that not every screen can be called programmatically and not in every place it can be called. For example, it is not recommended to call the default selection screen 1000 from code. However, selection screens will be discussed further. We already know that classical screens are both programmatic and visual objects, but how they are created? For this purpose, one can use the usual development transaction SE80 or a special transaction SE51, called Screen Painter. SAP Screen Painter Transaction Here, one can edit and create screens using different approaches: by specifying attributes, by direct graphical painting and by editing layout. Editing Screen Layout Basic screen elements that can be placed onto the screen are: • Check Box • Text Field • Push Button • Input Field • Radio Button • Tabstrip Control • Table Control • Custom Control Here we do not dive into the GUI controls details and will review them in the future tutorials.

The thing is pretty self-explanatory and lies in the name: they are used for selection of data from database. Classic screens can carry this function too but selection screens do this significantly better and here is why: they do not need to be created in advance but are rather declared via a set of declarative statements. This makes development process more robust, rapid and allows to fulfill routine reporting tasks more easily. The main declarative screen for selection screen is created like this: SELECTION-SCREEN BEGIN OF SCREEN ssn. SELECTION-SCREEN END OF SCREEN ssn. Where ssn is the screen number. Corresponding declarative statements for different selection controls are listed below. Empty line for division of different controls on the screen is declared like this.
