Internal Table Data Created in a Class=>Method?

[Former Member]

Anyway to store this Internal Table in the Class Memory? So when I return to another Method within the Class during Runtime the Internal table still holds its values?

Thank-You

Hello,

No problem - you have to declare the table as "Static Attribute"

Even easier

Create a dynamic table . This is then available in your entire program plus all methods in a class call

For example

program zzz_simple_dynamic_table.

* Define any structure
types:  begin of s_elements,
  vbeln   type vapma-vbeln,
  posnr   type vapma-posnr,
  matnr   type vapma-matnr,
  kunnr   type vapma-kunnr,
  werks   type vapma-werks,
  vkorg   type vapma-vkorg,
  vkbur   type vapma-vkbur,
  status  type c,

end of  s_elements.

* end of your structure

data lr_rtti_struc type ref to cl_abap_structdescr .
data:
    zog                     like line of lr_rtti_struc->components .
data:
  zogt                    like table of zog,
wa_it_fldcat type lvc_s_fcat,
it_fldcat type lvc_t_fcat ,
dy_line            type ref to data,
dy_table           type ref to data.


data:  dref               type ref to data.
field-symbols: <fs> type any,
   <dyn_table>    type  standard table,
   <dyn_wa>.

data grid_container1 type ref to cl_gui_custom_container .
data grid1 type ref to cl_gui_alv_grid .
data: ok_code type sy-ucomm.
data: struct_grid_lset type lvc_s_layo.

*now I want to build a field catalog
* First get your data structure into a field symbol

create data dref type s_elements.
assign dref->* to <fs>.

lr_rtti_struc ?= cl_abap_structdescr=>describe_by_data( <fs> ).

* Now get the structure details into a table.
* table zogt[] contains the structure details
* From which we can build the field catalog

zogt[]  = lr_rtti_struc->components.
loop at zogt into zog.
  clear wa_it_fldcat.
  wa_it_fldcat-fieldname = zog-name .
  wa_it_fldcat-datatype = zog-type_kind.
  wa_it_fldcat-inttype = zog-type_kind.
  wa_it_fldcat-intlen = zog-length.
  wa_it_fldcat-decimals = zog-decimals.
  wa_it_fldcat-coltext = zog-name.
  wa_it_fldcat-lowercase = 'X'.
  append wa_it_fldcat to it_fldcat .
endloop.
*
* You can perform any modifications / additions to your field catalog
* here such as your own column names etc.

* Now using the field catalog created above we can
* build a dynamic table
* and populate it

* First build the dynamic table
* the table will contain entries for
* our structure defined at the start of the program

call method cl_alv_table_create=>create_dynamic_table
       exporting
            it_fieldcatalog = it_fldcat
       importing
            ep_table = dy_table.


assign dy_table->* to <dyn_table>.
create data dy_line like line of <dyn_table>.
assign dy_line->* to <dyn_wa>.

* Now fill our table with data

select vbeln posnr matnr kunnr werks vkorg vkbur
       up to 200 rows
       from vapma
       into  corresponding fields of table <dyn_table>.

Now values in <dyn_table> will be available throughout your code.

If you want to transfer to a "Classical table'

then just use something like

int_table[] = <dyn_table>.

The same code will work if it's in a method.

As you are using a field symbol you shouldn't even need to pass the value as a parameterr.

Once the field symbol is assigned it's available everywhere in your code.

Just ensure you have defined the field symbol before using in a method

Hello Jimbo,

I have tested your example now.

It is very good. Thank you.

Hi Tom,

Yes i think it is possible to store internal table in the Class memory.

But you faced that problem as i think when you return to the another method please clear the data which internal table already holds.

CLEAR <INTERNAL TABLE NAME>.

and then return to the another method.

Sayak.... "if it useful to you pls reward"
