Define work area with referencing to dynamic structure name

[Former Member]

Hi,

I need help on defining a work area with referencing to a dynamic structure name. Could you please help?

Thanks,

You need to use the field-symbols to get an access of the dynamica structure. Insdie the loop, you need to access each field individually using the Field symbols.

Like:

  FIELD-SYMBOLS: <LT_TEXT>     TYPE ANY TABLE,
                 <LA_TAB>      TYPE ANY,
                 <LF_ITEXT>    TYPE ANY.

  LOOP AT <LT_TEXT> ASSIGNING <LA_TAB>.
    ASSIGN COMPONENT: 'FIELD1'    OF STRUCTURE <LA_TAB>  TO <LF_ITEXT>.

  ENDLOOP.

This is how you can do this.

<line> will be your work area.

DATA: l_struct    TYPE REF TO data.

FIELD-SYMBOLS: <table>  TYPE STANDARD TABLE, " Dynamic Table
                            <line>   TYPE ANY.

CREATE DATA l_struct LIKE LINE OF <table>.
ASSIGN l_struct->* TO <line>.

One simple approach can be using class cl_alv_table_create.

data: i_table type ref to data.

field-symbols : <list> type table .

call method cl_alv_table_create=>create_dynamic_table

exporting

it_fieldcatalog = lt_alv_cat

importing

ep_table = i_table .

assign i_table->* to <list> .

Enjoy SAP.

simplest way to create a work area for your dynamic table

data: l_wa_ref type ref to data.

"Create a data
 create data l_wa_ref like line of <f_data>.

I have a string of 2000 chars that will be populated with different formats and I need to dynamicly define a work area (wa) so I can map the data from the string to my work area. I am having a difficulty in defining such work area.

For example,

String can have data of VBAK or VBAP and I need a work area defined accordingly for my mapping like

wa = string.

Please help,

Thanks!

Check this coding:

PARAMETERS:
  p_type TYPE typename OBLIGATORY DEFAULT 'VBAK'.
DATA:
  gr_dataref  TYPE REF TO data.
FIELD-SYMBOLS:
  <gfs> TYPE ANY.

CREATE DATA gr_dataref TYPE (p_type).
ASSIGN gr_dataref->* TO <gfs>.

<gfs> will take the structure from the name parameter, in this case table VBAK by default.

So if you have VBAK data in your string, doing the assignment <gfs> = string would split the data over the different fields.

What this code is lacking is exception handling, which depends on the SAP version you're at.

If your WAS is >= 6.20, you can use exception classes, so you should catch exception CX_SY_CREATE_DATA_ERROR:

TRY.
  CREATE DATA gr_dataref TYPE (p_type).
    CATCH CX_SY_CREATE_DATA_ERROR.
      " Exception handling in here
ENDTRY.

On older releases you should use CATCH SYSTEM-EXCEPTIONS ... ENDCATCH instead.
