[ABAP] learning summary - common statements and functions

-----------------------Pointer------------------------ Pointer FIELD-SYMBOLS ================================ Loop the inner table into the pointer: 1. FIELD-SYMBOLS:<fs_data> LOOP AT gt_data ASSIGNING <fs_data>. 2. LOOP AT gt_data ASSIGNING FIELD-SYMBOL(<fs_data>). Pointer to allocate component: 1. ASSIGN COMPONENT OF STRUCTURE workspace to < FS > *You can specify < comp > as text or variable. If < comp > is of type C or string, it is the name of the specified component. *If < comp > has any other basic data type, it is converted to type I and refers to the component number. If the allocation is successful, SY-SUBRC is 0, otherwise it is 4. ================================ Usage and comparison of FIELD SYMBOL and TYPE REF TO ================================ TYPE REF TO can only connect to data or object Need to open memory CREATE DATA or CREATE OBJECT 1, Definition The definition of Type Ref To and Field Symbol can specify a specific type or structure, or not. 01 data ref type ref to data 02 03 DATA ref TYPE REF TO ty_ym. "Specify specific structure 04 05 data ref type ref to char20 06 07 field-symbols < FS > type any table 08 09 FIELD-SYMBOLS < FS > TYPE it_ YM. "Specify a specific table 10 11 field symbols < FS > type any. "No specific type or structure is specified, either structure or type 12 13 FIELD-SYMBOLS < FS > TYPE ty_ YM. "Specify specific structure 14 15 field-symbols < FS > type char20 2, Initialization There are two initialization methods for Type Ref To: The first is to use CREATE DATA to dynamically open memory; The second is to use GET REFERENCE OF to point to an existing memory variable The initialization of the Field Symbol can only point to memory variables that already exist. 01 CREATE DATA ref TYPE ty_ym. 02 03 CREATE DATA ref LIKE LINE OF it_ym. 04 05 CREATE DATA ref LIKE wa_ym. 06 07 CREATE DATA ref LIKE ym. If ref is defined to specify a specific TYPE or structure, TYPE can be omitted when creating data. No matter whether ref has a specific type or structure when defining, you must specify a specific type or structure when creating data. It cannot be a generic type such as data. 01 ASSIGN wa_ym to < FS >. "Initialization of field symbol, the effect is equivalent to pointing to wa_ym 02 03 ASSIGN v_ym to < FS >. "Initialization of field symbol, the effect is equivalent to pointing to v_ym 04 05 GET REFERENCE OF wa_ym into Ref. "initialization of type ref to is equivalent to pointing to wa_ym 06 07 GET REFERENCE OF v_ Initialization of YM INTO Ref. "Type Ref To_ YM Must be initialized before using Field Symbol and Type Ref To, otherwise RUNTIME ERROR will occur. 3, Use If a specific type or structure is specified in the first step of definition, Field Symbol and Type Ref To can be used directly; If no type or structure is specified in the first step of definition, then Type Ref To must be assigned to another Field Symbol for indirect use. 1) When specifying a specific type: 01 ref->* = 'abc'. 02 < fs > = 'abc'. 2) When specifying a specific structure: 01 ref - > 02 < fs >-col1 = 'abc'. 3) When no specific type or structure is specified: 01 FIELD-SYMBOLS < FSX > TYPE ty_ym 02 assign ref - > * to < FSX >. "Universal structure 03 < FSX >-col1= 'abc'. 04 05 FIELD-SYMBOLS < FSX > TYPE any. " 06 assign ref - > * to < FSX >. "Universal type 07 < FSX > = 'abc'. 08 09 FIELD-SYMBOLS < FSX > TYPE any. " 10 assign component 'col1' of structure < FS > into < FSX > 11 < FSX > = 'abc'. matters needing attention: Generally speaking, for the convenience of use, the type or structure of Field Symbol or Type Ref To should be specified for direct use later. When using Type Ref To, if it is TYPE REF TO DATA, the Field Symbol will be inevitably used when you want to use this Type Ref To later; In this way, the code is very cumbersome to write. It's better to use Field Symbol in the beginning. However, in the case of a dynamic internal table that does not know the structure in advance, only Type Ref To can be used, combined with Field Symbol; If the Field Symbol is used directly, the Field Symbol cannot be initialized with reference to an existing structure. If the first step is TYPE REF TO DATA, the second step after initialization still needs to specify a specific structure, so it's not as good as specifying the structure in the first step. It is recommended that you use generic definitions only if you do not know the structure in advance. Therefore, either type or structure is specified during definition and initialization, or dynamic inner table or structure cannot be specified in advance; Like the first step TYPE REF TO DATA the second step CREATE DATA ref TYPE ty_ym is not a good way. 4. Differences The main differences found in the usage of Type Ref To and Field Symbol are as follows: 1) Type Ref To can dynamically open memory. In dynamic internal table, it can wait for the program to obtain the structure at runtime before opening memory, and assign it to a Field Symbol. It is impossible to use Field Symbol alone, because the initialization of Field Symbol needs to be "hung" on a known structure. 2) Type Ref To does not have loop at it like Field Symbol_ For the writing method of tab designing < FS >, ref - > * does not point to the inner table data, It is similar to a work area that points to a block of memory, so you need to modify the data to the internal table after you change it. If you don't need the data, you need to clear. Field symbols do not need to consider modify and clear. 3) If < FS1 > = < fs2 > is the value in comparison memory, corresponding to if REF1 - > * = ref2 - >. ================================ -----------------------Internal table------------------------ Delete address duplicates from comparing

Field 2 of field 1 of COMPARING table in delete assistant duplicates from
#According to the field de duplication after COMPARING, sort and use according to these fields first, and keep the first one

SORT inner table from small to large

SORT inner table [BY key 1 Key 2 ] [STABLE] [DESCENDING]
#For rows with the same keyword, the STABLE keyword can keep the original order after sorting
#DESCENDING (from large to small)

Determine whether there is any data in the internal table READ TABLE [index|with key] transportation no fields ================================ READ TABLE [index|with key] transportation no fields It is only to determine whether there is secondary data in the inner table, and it is not necessary to read it into the workspace. If the inner table can read the data, sy subrc = 0 ================================ Statistics inner table row number Description Access the internal standard attribute and assign the number of rows to the variable: description table internal table LINES variable (integer or N) sum number field COLLECT in the inner loop table The COLLECT statement is invoked in the loop, and the same string will gather its numeric field. ================================ LOOP AT gt_data INTO gs_data. COLLECT gs_data INTO gt_sum. ENDLOOP. For example: gt_data data: A Shandong 1 A Shandong 3 B Beijing 4 B Beijing 2 B Beijing 6 A Shandong 2 B Beijing 1 B Beijing 3 After processing gt_sum data: A Shandong 6 B Beijing 16 ================================ String type ` ‘…’ ================================ `... 'is the original string (similar to r' 'in python) '...' is a normal string ================================ -----------------------String------------------------ Concatenate & && ================================ 1. CONCATENATE str1 str2 ...|LINES OF itab INTO result [SEPARATED BY sep] [RESPECTING BLANKS]. The leading spaces of CDNT type will be reserved, and the trailing spaces will be removed, but all spaces of String type will be reserved; For strings of type c, d, n, t, there is a spacing blanks option to use, indicating that trailing spaces will also be reserved. Note: the trailing space will be reserved when using ` ` to assign a String type 2. str = str1 && str2 &&Operator (can break the 255 character limit) 3. str = str1 && str2 &Operator (cannot exceed 255 character limit) ================================ SPLIT string ================================ Take '.' as the separator, and put the separated string into the inner table with only one column, for example: SPLIT str AT '.' INTO TABLE ================================ String to space CONDENSE
================================ CONDENSE <c> [NO-GAPS]. 1. If it is C The type only removes the space in front (because it is fixed length, even if the space in the back is removed, the space will be filled after the left alignment); 2. If it is String Type, the space after will also be removed; 3. Multiple consecutive spaces in the middle of a string are replaced with one space(String So is the type)； 4. NO-GAPS: All spaces in the middle of the string are also removed(String So is the type)； 5. Left aligned when spaces are removed ================================
SEARCH string search ================================ Search for < C > in < STR > SEARCH <c> FOR <str> <options>. If successful, set SY-SUBRC to 0 and SY-FDPOS to the offset of the string in the field < C >. Otherwise, set SY-SUBRC to 4. ================================ Replace string replace [all occurs of regenx] regex in dobj with new ================================ REPLACE [ALL OCCURRENCES OF REGEX] regex IN dobj WITH new Replace the first [all] regex in dobj with new ================================ String match CO/CN CA/NA CS/NS CP/NP ================================ CO contain only str1 CO str2 Traversal str1, where each character exists in str2, returns true For example: str1 = 'I a' STR2 = 'hub' ----- false str1 = 'ba' str2='hubab' -----true CA contain any str1 CA str2 Traverse str1, and return true if there is a character in str1 in str2 For example: str1 = 'I a' STR2 = 'hub' ----- true CS contain string str1 CS str2 Determine if str1 contains str2. CP contains pattern str1 CP str2 After the comparison, if the result is true, sy fdpos will give the offset information of s2 in s1 str1 = 'aac' str2 = '#aA#c' true str1 = 'aAc' str2 = '#aA#c' true str1 = '123abc123' str2 = '*abc*' sy-fdpos = 3. pattern matching CO / CN contains only or not CA / NA contains any or not any CS / NS contain string or not CP / NP contains pattern or not ================================ CORRESPONDING operation between structures MOVE-CORRESPONDING ADD- SUBTRACT- MULTIPLY- DIVIDE- -----------------------DATA&TYPE------------------------ Define TYPES to INCLUDE
================================ TYPES: BEGIN OF ty_data, fldate TYPE sflight-fldate. INCLUDE TYPE spfli. TYPES: END OF ty_data. ================================

LIKE LINE OF Internal table. ================================
-----------------------Loop control and standard statements------------------------ Global breakpoint BREAK username BREAK user name: the user name will BREAK here every time the program runs Cycle / subprogram control CHECK|EXIT|CONTINUE 1. CHECK condition: if the condition is true, execute the following code, otherwise jump out of the loop (end subroutine in subroutine) 2. EXIT: jump out of loop (end subroutine in subroutine) 3. CONTINUE: jump out of this cycle Exception capture TRY ================================ 1. Syntax: DATA: exref TYPE REF TO CX_ROOT. TRY. Statement block CATCH general exception (CX_SY_ARITHMETIC_ERROR) INTO exref. Exception handling statement block after capture CATCH exception name (example CX_CX_SY_CONVERSION_NO_NUMBER) INTO exref. Exception handling statement block after capture CLEANUP. Clean statement block after any exception is caught ENDTRY. 2. Properties and methods of exref: Textid Property that defines the different text of the exception and also affects the method get_text. Previous Property, which stores the original exception and allows you to build an exception chain get_text Method, which returns the text representation as a string based on the system language of the exception. get_longtext Method, which returns the long variant of the text representation of the exception as a string. get_source_position Method, returns the program name and line number that threw the exception. ================================ CLEAR REFRESH FREE ================================ CLEAR Clear only the table work area. To reset the entire inner table without clearing the table workspace, use clear < itab > [] without freeing up space REFRESH If you add brackets or not, you can only clear the inner table. REFRESH is specifically for clearing the inner table. It cannot clear basic type variables and does not release space FREE At the same time of initialization, the space occupied shall be released. The usage is the same as that of CLEAR ================================ Memory variable EXPORT|IMPORT internal variable = change TO MEMORY ID 'memory name' ================================ 1. ABAP memory variables are similar to local variables, which can be used to communicate between main processes and subprocesses. Different external sessions have different memory spaces Store data in memory: EXPORT internal variable 1 = variable 1 internal variable 2 = variable 2 TO MEMORY ID 'memory name' Read data from memory: IMPORT internal variable 1 = change 3 internal variable 2 = change 4 FROM MEMORY ID 'memory name' Clear all ABAP memory variables: FREE MEMORY. Clear the specified ABAP memory variable: FREE MEMORY ID 'memory name' 2. SAP memory variables are similar to global variables. They are used for communication between external sessions.
