Abap Technical Interview Questions 3

What is a Spool request? Spool requests are generated during dialog or background processing and placed in the spool database with information about the printer and print format. The actual data is places in the Tem Se (Temporary Sequential objects). What is a Data Class? The Data class determines in which table space the table is stored when it is created in the database. What is a Size Category? The Size category describes the probable space requirement of the table in the database. How many types of size categories and data classes are there? There are five size categories (0-4) and 11 data classes only three of which are appropriate for application tables: • APPL0- Master data (data frequently accessed but rarely updated). • APPL1- Transaction data (data that is changed frequently). • APPL2- Organizational data (customizing data that is entered when system is configured and then rarely changed). The other two types are: • USR • USR1 – Intended for customer’s own developments. A field containing quantity amounts (data type QUAN) must be assigned to a reference table and a reference field. Explain? As a reference table, a system table containing all the valid quantity units is assigned or any other table, which contains a field with the format or quantity units (data type UNIT). This field is called as reference field. The assignment of the field containing quantity amounts to the reference field is made at runtime. The value in the reference field determines the quantity unit of the amount. Can we include customizing include or an append structure with Pooled or Cluster tables? No. Name the display and update modes in the case of call transaction. – Display all (A), display none (N), display error only (E). Synchronous Update (S) and Asynchronous Update (N). In case of call transaction update occurs after _____________ and in case of call dialog update occurs __________. – Transaction is completed, on COMMIT statement. Name the different list display events. – at pf ##, at line-selection, at user-command.

When do the above events get fired? – at pf ##: function key pressed, at line-selection: double click or single click and f2, at user-command: click on a push button or click on a menu item. When the user selects a line in the report, the field ________ is updated with the text from the line. – Sy-lisel. Name the different Conditional Execution Flow Logic Additions. – On input, On request, at exit-command, at cursor-selection. What are the different types of windows? – Main, VAR and CONST. Distinguish between tag column and text line column. – Former specifies the format of the text and the latter contains the actual content of the window. A subroutine can be terminated upon a condition using CHECK Statement. The function modules are created and stored in the Function Library. What is meant by hotspots? A Hotspot is a list area where the mouse pointer appears as an upright hand symbol. When a user points to that area (and the hand cursor is active), a single click does the same thing as a double-click. Hotspots are supported from R/3 release 3.0c. What is the significance of the memory table ‘SCREEN’? At runtime, attributes for each screen field are stored in the memory table called ‘SCREEN’. We need not declare this table in our program. The system maintains the table for us internally and updates it with every screen change.
