  1. ABAP/4 Course

  2. General • Workbench • Program maintenance • Screen Painter • Menu Painter • Transactions • ABAP/4 Query • Translation menu

  3. ABAP/4 (SE38) • Change/Display • Variants • Attributes (Logical Data Bases) • Documentation • Text Elements • Program Directory • Copy/Rename/Delete • Development Test

  4. Development/Test • Run-time Analysis • Extended Syntax Check • Program References • Pretty Printer • Find Source String

  5. ABAP/4 Editor • Check/Generate • Insert Statement • Split Line/Copy/Move... • Fetch • Position • Goto Menu • Utilities (Local/Global Search) • Upload/Download • Set/Display Breakpoints • Printing (Only a part ...)

  6. Insert Statement • Select * from • Call Function • Message • Write • Others e.g. Comment(*, **1, *f, *m ...)

  7. ABAP/4 Debugger • Single Step/Execute/Continue • Table (PgUp/PgDn/Format E,C,X) • Click on fields (Change Contents or Display) • Scroll in program source • Goto Menu • Set/Delete Breakpoint (Breakpoint At)

  8. ABAP/4 Programming • = Event-driven programming language • Working with Reports • Report Syntax and layout • Declaring and Processing data • Events and Flow Control • Subroutines • Reading and Processing Internal tables/Database tables • Selection criteria and Parameters • Working with Logical Databases • Interactive Reporting

  9. Working with Reports • Naming a Report (R/Z + M/F... + Name(6)) • Creating Reports • Changing Reports

  10. Report Syntax and Layout • Structure of the ABAP/4 Programming Language • ABAP/4 Report Layout • Inserting Ready-Made Strucures

  11. Key Words • Declaratives (DATA,.) • Events (GET,...) • Control (IF,...) • Operational (WRITE,)

  12. Declaring and Processing data • Constants/Variables • Assigning Values • Arithmetic Operations • Processing Text Fields • System Fields (SY-UZEIT, SY-DATUM)

  13. Events and Flow Control • Event Key Words (GET, START/END OF SELECTION, INITIALIZATION) • Events: Concept • Flow Control in ABAP/4 • Flow Control: Concept

  14. Events: Concept

  15. Flow Control: Concept REPORT DEMO. <declaration section> START-OF-SELECTION. " processing block WRITE: 'Start', ... . GET LFA1. " processing block WRITE: ... . IF LFA1-LAND1 = 'D'. ... ENDIF. GET LFB1. " processing block WRITE: ... . END-OF-SELECTION. " processing block WRITE: 'Total:', ... .

  16. Subroutines • Definition • Calling Subroutines • Passing data between subroutines/reports (INCLUDE, PERFORM X(Y),...) • Function Modules

  17. Reading and Processing Internal Tables/Databases • Definition (Internal Tables) • Filling Internal Tables • Reading/Changing and Sorting • SELECT/INSERT/UPDATE/MODIFY/DELETE

  18. Simple Reading SELECT * FROM T005T WHERE LAND1 EQ 'D'. WRITE: T005T-SPRAS, T005T-NATIO.ENDSELECT.SELECT * FROM <dbtab> INTO TABLE <itab> [WHERE ...] [ORDER BY ...].Note that there is no ENDSELECT here. SELECT * FROM <dbtab> APPENDING TABLE <itab> [WHERE ...] [ORDER BY ...].If the operation was successful, the system field SY-SUBRC is set to 0, otherwise to 4.SELECT SINGLE * FROM <dbtab> WHERE ...In this case, the WHERE condition may contain only equality conditions linked using AND. You have to specify the primary key in full.

  19. Selection Criteria and Parameters • SELECT-OPTIONS • PARAMETERS • SELECTION-SCREEN

  20. Working with Logical Databases • Display/Maintenance • ABAP/4 Key words for Logical Databases • Concept

  21. Logical Data Bases • Structure • Selections/Texts • Database Program (SAPDB<dba>) • Selection Screen • Documentation • Checking/Copying/Deleting/Details
