Create structure dynamically by using table

Former Member — Mon, 20 Jan 2014 10:46:41 GMT

Hello,

I have a program with a structure which is defined as following:

TYPES:

    BEGIN OF test,

    0vtype(3)    TYPE n,

    0calmonth2(2)     TYPE n,

    0calyear(4)    TYPE n,

END OF test.

I'd like to create this structure dynamically. I have a table test_table which contains the objects. How could I create the structure dynamically by using the table?

Thanks in advance.

Best regards

Ella

data : it_tabdescr type abap_compdescr_tab,
wa_tabdescr type abap_compdescr.

data : ref_table_descr type ref to cl_abap_structdescr.

* Return structure of the table.
ref_table_descr ?= cl_abap_typedescr=>describe_by_name( p_table ).
it_tabdescr[] = ref_table_descr->components[].

Hi,

If you have the table then you can create a dynamic structure using that as follows.

FIELD-SYMBOLS: <lfs_rslt> TYPE any,

CREATE DATA lv_ref TYPE Line of Table_name.

ASSIGN lv_ref->* To <lfs_rslt>.

Use CL_ABAP_TYPEDESCR->DESCRIBE_BY_NAME or similar method to get every component description from your itab, then use CL_ABAP_STRUCTDESCR->CREATE to create the structure. There are already some threads and wiki with sample, use search tool.
