# ABAP Development Reference General ABAP language reference covering classical and modern ABAP (NW 7.40+). ## ABAP Syntax Basics ### Data Types | ABAP Type | Description | Length | Default | |---|---|---|---| | C | Character | 1-65535 | ' ' | | N | Numeric text | 1-65535 | '0' | | I | Integer | 4 bytes | 0 | | P | Packed number | 1-16 bytes | 0 | | F | Floating point | 8 bytes | 0.0 | | D | Date (YYYYMMDD) | 8 chars | '00000000' | | T | Time (HHMMSS) | 6 chars | '000000' | | STRING | Variable-length string | Dynamic | '' | | XSTRING | Variable-length byte | Dynamic | '' | ### Internal Tables ```abap " Standard table (unordered, fastest for appending) DATA: lt_materials TYPE STANDARD TABLE OF mara. " Sorted table (ordered by key, no duplicates) DATA: lt_materials_sorted TYPE SORTED TABLE OF mara WITH UNIQUE KEY matnr. " Hashed table (key access only, fastest for reads) DATA: lt_materials_hashed TYPE HASHED TABLE OF mara WITH UNIQUE KEY matnr. " Inline declaration DATA(lt_data) = VALUE string_table( ( 'A' ) ( 'B' ) ). " Append / Insert / Read / Modify / Delete APPEND ls_row TO lt_data. INSERT ls_row INTO TABLE lt_data. READ TABLE lt_data INTO DATA(ls) WITH KEY field = 'X'. MODIFY TABLE lt_data FROM ls. DELETE lt_data WHERE field = 'X'. ``` ### FIELD-SYMBOLS (Pointers) ```abap " Assign to structure ASSIGN COMPONENT 'MATNR' OF STRUCTURE ls_header TO FIELD-SYMBOL(<lv_matnr>). IF <lv_matnr> IS ASSIGNED. lv_result = <lv_matnr>. ENDIF. " Loop with field symbol (fastes
