Hi Vijaya,

Please change the select option to parameter as in the definition of method get_data IMPORTING v_vbeln TYPE vbak-vbeln, you are passing v_vbeln as a single value. If u want to pass a select option then u have to pass a table type like structure of a select option.

Please see the modified code..

REPORT zoops_vij .

TABLES : vbak.

PARAMETERS : s_vbeln LIKE vbak-vbeln.

Hope this solves ur problem.

Hi Vijaya,

I have noted some mistake .

1) METHODS : get_data IMPORTING v_vbeln TYPE vbak-vbeln,

disp_data.

Here get_data method import variable (V_VBELN)

CALL METHOD sales_obj->get_data

EXPORTING

v_vbeln = s_vbeln.

Here exporting V_VBELN = S_VBELN.

how it possible one variable can not store ranges value (Multiple value ). thats why problem occur.

If helpful give me rewards

Thanks
