Create a dynamic internal table name.

[Former Member]

Hello gurus,

I need to create an internal table in runtime. I don´t need to create the table catalog dynamically, I need to create the internal table name in a dynamic way. For example:

DO 25 TIMES
"CREATE AN INTERNAL TABLE WITH NAME 'IT_TABLE_'  + SY-TABIX.
"FILL THE TABLE
"ETC
ENDDO.

Thank you very much and kind regards

Ibai

Look at SAP Abap documentation for [CREATE DATA|http://help.sap.com/abapdocu_70/en/ABAPCREATE_DATA.htm] and [CREATE DATA - TABLE OF|http://help.sap.com/abapdocu_70/en/ABAPCREATE_DATA_ITAB.htm]. You could create an internal table of reference to internal tables for your kind of requirement.

Thanks Raymond,

I have already seen this, but It si not helpfull, I need to create an internal table with a dynamic name, not with a dinamic structure.

The structure is the same for each internal tabla, I just need tocreate any number of diferent internal tabls with diferente names,

Regars,

Then create an internal table of internal tables. (creating a table is appending in the main itab)

(I wrote nothing on dynamic structure ^^)

Hello,

Check this code snippet:

TYPES:
BEGIN OF gty_dyntab,
  name TYPE string,      "Int. table name
  data TYPE REF TO data, "Int. table data
END OF gty_dyntab.

DATA: gv_table  TYPE dd02l-tabname,
      gt_dyntab TYPE STANDARD TABLE OF gty_dyntab,
      gs_dyntab TYPE gty_dyntab,
      gv_index  TYPE numc2.

SELECT-OPTIONS: s_table FOR gv_table NO INTERVALS.

LOOP AT s_table.
* Populate the int. table name
  WRITE sy-index TO gv_index NO-ZERO.
  CONCATENATE 'IT_TABLE' gv_index INTO gs_dyntab-name.

* Create the int. table
  CREATE DATA gs_dyntab-data TYPE STANDARD TABLE OF (s_table-low).

  APPEND gs_dyntab TO gt_dyntab. CLEAR gs_dyntab.
ENDLOOP.

For the sake of simplicity i've used a simple version of CREATE DATA. Based on your requirement you can use this construct or the RTTC classes to generate the dynamic type.
