Hello.

> Does somebody know how can I get the names of the columns of an internal table at run time ? ?

> I mean:

> For example, if I create an internal table called ITAB1

> DATA: ITAB1 LIKE BKPF OCCURS 0,

> BEGIN OF ITAB2 OCCURS 0,

> FIELDNAME(40) TYPE C,

> END OF ITAB2.

> So, I want to full fill the internal table ITAB2

with all the names of the columns of the internal table ITAB1.

> But, I don't know how !! !

The function module GET_COMPONENT_LIST will give all the details of the columns of the table.

data : ref_descr type ref to cl_abap_structdescr.

ref_descr ?= cl_abap_typedescr=>describe_by_DATA( your_structure ).

data : it_details type abap_compdescr_tab,

wa_details type abap_compdescr.

it_details[] = ref_descr->components[].

loop at it_details into wa_details.

WRITE:/ WA_DETAILS-NAME.

ENDLOOP.

HEllo Selva,

U can use the FM GET_COMPONENT_LIST for this purpose.

If useful reward.
