Moving Parameter value into Workarea

Former Member — Fri, 08 Aug 2008 13:07:11 GMT

Hi Abapper,

I have to take the input of structures into the Parameter.

Now I have to define a workarea of the structure which are inputted into the Parameter.

How to do that?

Please reply

Rahul

You may use some of the following function module in a AT SELECTION-SCREEN ON VALUE REQUEST form.

- RS_COMPLEX_OBJECT_CHANGE

- RS_COMPLEX_OBJECT_CREATE

- [RS_COMPLEX_OBJECT_EDIT|https://www.sdn.sap.com/irj/sdn/advancedsearch?query=rs_complex_object_edit&cat=sdn_all]

- RS_COMPLEX_OBJECT_HEADER

- RS_COMPLEX_OBJECT_TREE

- RS_COMPLEX_OBJECT_TYPEINFO_GET

These are the "structure editor" function modules used when you test a function module, could look like

REPORT zrgstst.
PARAMETERS param LIKE t002.
AT SELECTION-SCREEN ON VALUE-REQUEST FOR param.
  CALL FUNCTION 'RS_COMPLEX_OBJECT_EDIT'
       EXPORTING
            object_name = 'T002'
            mode        = 'X'
       CHANGING
            object      = param.

Are you expecting similar kind of solution...

REPORT  ytest_dynamic.
 
TYPE-POOLS : abap.
DATA : table_des TYPE REF TO cl_abap_structdescr.
DATA : ifields TYPE abap_compdescr_tab,
          wa_field LIKE LINE OF ifields.
DATA: it_fieldcat TYPE lvc_t_fcat,
          wa_fieldcat TYPE lvc_s_fcat.
DATA: i_tab TYPE REF TO data.
 
FIELD-SYMBOLS: <fs> TYPE STANDARD TABLE.
 
PARAMETERS: p_table(30) TYPE c DEFAULT 'SFLIGHT'.
 
 
"Create the Table definiton using the table name
table_des ?= cl_abap_typedescr=>describe_by_name( p_table ).
"Transfer all the fields to a table.
ifields = table_des->components.
  
LOOP AT ifields INTO wa_field.
  CLEAR wa_fieldcat.
  wa_fieldcat-fieldname = wa_field-name .
  wa_fieldcat-datatype = wa_field-type_kind.
  wa_fieldcat-inttype = wa_field-type_kind.
  wa_fieldcat-intlen = wa_field-length.
  wa_fieldcat-decimals = wa_field-decimals.
  wa_fieldcat-coltext = wa_field-name.
  wa_fieldcat-outputlen = wa_field-length.
 
  APPEND  wa_fieldcat TO it_fieldcat.
ENDLOOP.
 
CALL METHOD cl_alv_table_create=>create_dynamic_table
  EXPORTING
    it_fieldcatalog           = it_fieldcat
  IMPORTING
    ep_table                  = i_tab
*    e_style_fname             =
