Dynamic variable creation.

soumya_jose3 — Thu, 04 Nov 2010 10:44:47 GMT

Hi,

Is there any method by which I can create variable names dynamically.

My requirement is to assign each of the values in the select option of the screen (p_stat) to separate variables.

Code is as shown below:

LOOP AT p_stat.

CLEAR: field, l_field.

l_field = sy-tabix.

CONCATENATE 'lv_text' l_field INTO field.

ASSIGN (field) TO <fs>.

<fs> = p_stat-low.

GET REFERENCE OF <fs> INTO wa_query-value_low.

APPEND wa_query TO gt_query.

ENDLOOP.

For the first loop pass, the value of p_stat has to be assigned to lv_text1, 2nd loop pass value to lv_text2 etc......

I was able to do so using field symbol. But here I have to then declare the variables like lv_text1, lv_text2 etc separately which will only be known (ie, the no: of variables to declare) only at the runtime.

Is there any solution.

Thanks & Regards,

Soumya.

Hello,

How did you define gt_query & wa_query?

Hi Suhas,

Decalartions are as follows:

DATA : gt_query TYPE mdm_query_table,

wa_query TYPE mdm_query.

Hi,

I do not know exactly what you want to do. If it helps you can create dinamyc tables with method cl_alv_table_create=>create_dynamic_table. I show you an example below.

FIELD-SYMBOLS: <fs_data> TYPE REF TO data.

FIELD-SYMBOLS: <fs_1> type table.

FIELD-SYMBOLS: <dat1> type data.

DATA: es_dfies LIKE LINE OF et_dfies.

CALL FUNCTION 'TR_NAMETAB_GET'

EXPORTING

IV_TABNAME = 'VIMFLAGTAB'

IV_GET_LENGTHS_IN_CHARMODE = 'X'
IV_GET_TEXTS = ' '

IMPORTING

ET_DFIES = et_dfies.

ES_HEADER =
EXCEPTIONS
NOT_FOUND = 1
OTHERS = 2

IF SY-SUBRC <> 0.

MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.

ENDIF.

CALL METHOD cl_alv_table_create=>create_dynamic_table

EXPORTING

it_fieldcatalog = lt

IMPORTING

ep_table = <fs_data>

EXCEPTIONS

generate_subpool_dir_full = 1

OTHERS = 2.

ASSIGN <fs_data>->* TO <fs_1>.

SELECT *

FROM (from_clause)

APPENDING TABLE <fs_1>

WHERE (where_clause).

LOOP AT <fs_1> ASSIGNING <dat1>.

DO.

READ TABLE ET_DFIES INTO es_dfies INDEX sy-index.

ASSIGN COMPONENT es_dfies-fieldname OF STRUCTURE <dat1> TO <data>.

IF SY-SUBRC NE 0.

EXIT.

ENDIF.

ENDDO.

ENDLOOP.

Hello,

I don't find these DDIC elements in my system. Are these specific to MDM?

Anyway why don't you create an internal table of REF TO DATA & store the data references(via GET REFERENCE) as lines of the internal table.

Check the example provided in this SAP online documentation for further details:[http://help.sap.com/abapdocu_70/en/ABAPGET_REFERENCE.htm]

Hello you can try like this. Make changes as necessary . Just in se11 search for data element * XX * and use the required one.


DATA:li_index(2) TYPE n,
wf_str TYPE REF TO data.

FIELD-SYMBOLS:<fs> TYPE ANY.

DATA:lf_element TYPE REF TO cl_abap_elemdescr,
i_tot_comp TYPE cl_abap_structdescr=>component_table,
la_comp LIKE LINE OF i_tot_comp ,
lf_new_type TYPE REF TO cl_abap_structdescr.

DO 10 TIMES.
  CLEAR i_tot_comp[].
  li_index = sy-index.
  lf_element ?= cl_abap_elemdescr=>describe_by_name( 'CNTXX_KK' ).
  CONCATENATE 'CNT' li_index '_KK' INTO la_comp-name.
  la_comp-type =
    cl_abap_elemdescr=>get_i(  ).
  APPEND la_comp TO i_tot_comp.
  TRY.
      lf_new_type = cl_abap_structdescr=>create( i_tot_comp ).
    CATCH cx_sy_struct_creation .                       "#EC NO_HANDLER
  ENDTRY.
  CREATE DATA wf_str TYPE HANDLE lf_new_type.
  ASSIGN wf_str->* TO <fs>.
ENDDO.
