hi you can create a dynamic internal table by creating fieldcatalog and passing it to a cl_alv_table_create=>create_dynamic_table.

here in my question for the import parameter i had given type as table.

when i call from any program and pass the internal table of that program.this import parameter will be having that internal table structure.in that case i have to code for a dynamic internal table Rt.please suggest.

HI ,

U can follow the following steps:

Create instances of class cl_rs_where, Use the method add_line for building select and where clause dynamically.

For example

Create object for SELECT

CREATE OBJECT lr_select.

CALL METHOD lr_select->add_line

EXPORTING

i_line = rv_fieldname.

Create object for WHERE

CALL METHOD l_r_where->add_line

EXPORTING

i_line = rv_lang_field.

CALL METHOD l_r_where->add_line

EXPORTING

i_line = '='.

CALL METHOD l_r_where->add_line

EXPORTING

i_line = 'SY-LANGU'.

Call the select query

TRY.

SELECT (lr_select->n_t_where)

FROM (lv_table)

INTO CORRESPONDING FIELDS OF TABLE <itab>

WHERE (l_r_where->n_t_where).

CATCH cx_sy_dynamic_osql_semantics INTO l_r_excp.

ENDTRY.

Finally build the required internal table

IF <itab> IS NOT INITIAL.

LOOP AT <itab> ASSIGNING <row>.

ASSIGN COMPONENT rv_fieldname OF STRUCTURE <row> TO <fieldname>.

lw_value-key_value = <fieldname>.

ASSIGN COMPONENT rv_text_field OF STRUCTURE <row> TO <textfield>.

lw_value-text = <textfield>.

ENDIF.

APPEND lw_value TO rt_values.

ENDLOOP.

Thanks
