# ABAP Practical Learning

Practical work for learning ABAP Language concepts

Topics to cover:

* string operations: CONCATENATE, SPLIT, CONDENSE, SHIFT, FIND, substrings

* using string comparison operators CO,CN,CA,NA,CS,NS,CP,NP with special characters (*,+ and #).

* operations with internal tables and work areas: APPEND, LOOP, MODIFY, DELETE, READ TABLE, CLEAR, REFRESH, DESCRIBE TABLE, SORT

* understand the types of internal tables: standard, sorted and hashed

* understand the difference between internal tables with header lines (obsolete as of now) and internal tables without header lines.

* using selection screens (input screens) with parameters and screen-options

* using screen blocks and understanding the internal table behind the select-options

* using sy-uline and sy-vline system variables to draw boundaries of the tables in classic reports style

* use best performance guidelines with ABAP Programming (e.g. parallel cursors when dealing with nested loops)

* using events in classic reports of ABAP :

  * INITIALIZATION,

  * AT SELECTION-SCREEN OUTPUT,

  *  AT SELECTION-SCREEN,

  *   START-OF-SELECTION,

  *   TOP-OF-PAGE,

  *   END-OF-PAGE,

  *   END-OF-SELECTION.

  *   AT SELECTION-SCREEN ON VALUE REQUEST FOR .

  *   AT SELECTION-SCREEN ON HELP REQUEST FOR .

  *   AT SELECTION-SCREEN ON .

 * creating interactive classic reports and the use of events:

    * AT LINE SELECTION

 * how to use field symbols with data objects in ABAP
