dynamic Ranges

[Former Member]

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

<b>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...</b>

TYPE-POOLS: abap.

      lt_component   TYPE abap_component_tab,         "Tabelle der Strukturbeschreibung

* (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 = '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>

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.

[Former Member]

yes we can ..

<b>RANGES tables</b>

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>.

or

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

<b>

This defines internal standard tables whose line type is a structure as follows:</b>

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

<b>This statement is simply a shortened form of the following statements:</b>

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

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.
