dynamic Ranges

Former Member — Thu, 12 Jul 2007 13:19:30 GMT

Hello,

i would like to create an internal range table about a table, which Name is in a Field.

I had create a Table with following Fields:

FALL CHAR10

LFDNR INT2

ZUORD CHAR5

FNAME M_COMB_FNAME

SIGN SIGN

OPTIO OPTION

HIGH HIGH_RANGE

LOW LOW_RANGE

At first i would like to create an internal range table, about a table which name is standing in the Field FNAME. And if there is a new Tablename in the Field FNAME, than i would like to create a new internal range table.

My suggestions are:

At First to create a Fieldsymbol:

assign (FNAME) to ).

And now, to create the new range table.

But How?

there are "create data", but it´s not working.

And then to fill the range table...

Is there anybody, who could help me.

Thanks.

Hi see the below code .... all Your 4 steps

1.At First to create a Fieldsymbol:

2.then, to identify the typ

3.to create the new range table.

4.to fill the range table...

TYPE-POOLS: abap. 


DATA: ls_component   TYPE abap_componentdescr,        "Zeile der Strukturbeschreibung 
      lt_component   TYPE abap_component_tab,         "Tabelle der Strukturbeschreibung 
      lr_strucdescr  TYPE REF TO cl_abap_structdescr, "Referenz auf Datentyp der Struktur 
      lr_tabledescr  TYPE REF TO cl_abap_tabledescr,  "Referenz auf Datentyp der Tabelle 
      lr_data_struct TYPE REF TO data,                "Referenz auf die erzeugte Struktur 
      lr_data_table  TYPE REF TO data,                "Referenz auf die erzeugte Tabelle 
      l_count        TYPE        i.                   "Anzahl Komponenten 

FIELD-SYMBOLS:  <fs_comp>   TYPE ANY,                  "Um auf eine Komponente zu zugreifen 
                <fs_struct> TYPE ANY,                  "Um auf die Struktur zu zugreifen 
                <fs_table>  TYPE ANY TABLE.            "Um auf die Tabelle zu zugreifen 

* (1) identify components required in your dynamic table 
CLEAR ls_component. 
ls_component-name = 'CARRID'. 
ls_component-type ?= cl_abap_typedescr=>describe_by_name( 'SFLIGHT-CARRID' ). 
INSERT ls_component INTO TABLE lt_component. 


CLEAR ls_component. 
ls_component-name = 'CONNID'. 
ls_component-type ?= cl_abap_typedescr=>describe_by_name( 'SFLIGHT-CONNID' ). 
INSERT ls_component INTO TABLE lt_component. 

CLEAR ls_component. 
ls_component-name = 'FLDATE'. 
ls_component-type ?= cl_abap_typedescr=>describe_by_name( 'SFLIGHT-FLDATE' ). 
INSERT ls_component INTO TABLE lt_component. 

* (2) create structure description in accordance to componentdata: 
IF lt_component IS NOT INITIAL. 
  lr_strucdescr = cl_abap_structdescr=>create( lt_component ). 
ENDIF. 

* (3) create table description for structure descriptiondata: 
lr_tabledescr = cl_abap_tabledescr=>create( p_line_type = lr_strucdescr ). 

* (4) create structure and assign 
CREATE DATA lr_data_struct TYPE HANDLE lr_strucdescr. 
ASSIGN lr_data_struct->* TO <fs_struct>. 

* (5) create table and assign 
CREATE DATA lr_data_table TYPE HANDLE lr_tabledescr. 
ASSIGN lr_data_table->* TO <fs_table> . 

* (6) fill table (from database) 
SELECT * FROM sflight INTO CORRESPONDING FIELDS OF TABLE <fs_table>. 

* (7) output 
l_count = LINES( lt_component ). 

LOOP AT <fs_table> INTO <fs_struct>. 
  DO l_count TIMES. 
    ASSIGN COMPONENT sy-index OF STRUCTURE <fs_struct> TO <fs_comp>. 
    IF sy-index = 1. 
      WRITE: / <fs_comp>. 
    ELSE. 
      WRITE: <fs_comp>. 
    ENDIF. 
  ENDDO. 

ENDLOOP. "<fs_table>  INTO <fs_struct>

reward points if it is usefull...

Thanks four your big help.

Your Answer was very helpfull.

But it´s possible to create a real rangetable (like DATA: variable TYPE RANGE OF TABLE) with this structure (lr_strucdescr or lr_tabledescr) and the structure from any table.

yes we can ..

RANGES tables

You can use the following variants of the TYPES and DATA statements to create internal tables of the same type as selection tables.


TYPES|DATA <rangetab> TYPE RANGE OF <type>.

TYPES|DATA <rangetab> LIKE RANGE OF <obj>.

This defines internal standard tables whose line type is a structure as follows:

SIGN(1) TYPE C 
OPTION(2) TYPE C 
LOW TYPE <type> bzw. LIKE <obj> 
HIGH TYPE <type> bzw. LIKE <obj>

This statement is simply a shortened form of the following statements:

DATA: BEGIN OF <rangetab> OCCURS 0,
         sign(1) TYPE c,
         option(2) TYPE c,
         low  LIKE <f>,
         high LIKE <f>,
      END OF <rangetab>.

please seee this link @ page no.8

it´s not possible.

TYPES|DATA have to be a real Table and the Tablename standing in a variable in my case.

And i only know the structure like lr_strucdescr or lr_tabledescr.
