Dynamic Range

Former Member — Fri, 02 Jan 2009 17:48:55 GMT

Hi,

I want to create a dynamic range in my program.

e.g I have an input field where a user can enter a FIELDNAME....

In my program I want to be able to create a 'RANGE' for this field with LOW, HIGH, SIGN & OPTIONs...

So the range needs to be dynamically created....

Can anyone help me in this?

Thanks,

Sanjiv

Just create an internal table with the appropriate fields and types.

TYPE-POOLS:
  abap.

DATA:
  gr_structdescr    TYPE REF TO cl_abap_structdescr,
  gr_tabledescr     TYPE REF TO cl_abap_tabledescr,
  gr_datadescr      TYPE REF TO cl_abap_datadescr,
  gr_typedescr      type ref to cl_abap_typedescr,
  gt_components     TYPE abap_component_tab,
  gw_component      TYPE LINE OF abap_component_tab,
  gr_wa             TYPE REF TO data,
  gr_tab            TYPE REF TO data.

FIELD-SYMBOLS: <fs_wa> TYPE ANY.
FIELD-SYMBOLS: <fs_tab> TYPE table.

PARAMETERS: p_field type fieldname.

START-OF-SELECTION.

* determine components of structure -> GT_COMPONENTS
  MOVE 'SIGN' TO gw_component-name.
  gw_component-type ?= cl_abap_elemdescr=>get_c( p_length = 1 ).
  INSERT gw_component INTO TABLE gt_components.

  MOVE 'OPTION' TO gw_component-name.
  gw_component-type ?= cl_abap_elemdescr=>get_c( p_length = 2 ).
  INSERT gw_component INTO TABLE gt_components.

  MOVE 'LOW' TO gw_component-name.
  gw_component-type ?= cl_abap_elemdescr=>describe_by_name( p_field ).
  INSERT gw_component INTO TABLE gt_components.

  MOVE 'HIGH' TO gw_component-name.
  gw_component-type ?= cl_abap_elemdescr=>describe_by_name( p_field ).
  INSERT gw_component INTO TABLE gt_components.

* get structure descriptor -> GR_STRUCTDESCR
  gr_structdescr ?= cl_abap_structdescr=>create( gt_components ).

* create work area of structure GR_STRUCTDESCR -> GR_WA
  CREATE DATA gr_wa TYPE HANDLE gr_structdescr.
  ASSIGN gr_wa->* TO <fs_wa>.

  gr_datadescr ?= gr_structdescr.
  gr_tabledescr ?= cl_abap_tabledescr=>create( gr_datadescr ).

* Create dynmaic internal table
  CREATE DATA gr_tab TYPE HANDLE gr_tabledescr.
  ASSIGN gr_tab->* TO <fs_tab>.

In this example, <fs_tab> would be your range, since ranges are nothing more than internal tables.

Regards,

Rich Heilman
