Hi
I have data in a dynamic table, whose structure is decided on runtime, now how can I pass this dynamic table to metod set_table_for_first display to use its data for alv display?

Hi,
check my code in
https://wiki.sdn.sap.com/wiki/x/_oCtAg
instead of assgn component you send it to ALV

Hi Rohit,
Why not use Class CL_SALV_TABLE. You don't need to know the structure of the table for this class.
DATA:
gr_table TYPE REF TO cl_salv_table.
CALL METHOD cl_salv_table=>factory
EXPORTING
list_display = if_salv_c_bool_sap=>false
* r_container =
* container_name =
IMPORTING
r_salv_table = gr_table
CHANGING
t_table = <table>
.
CALL METHOD gr_table->display
.

Yes, you can definatly pass the dynamic table, which I believe is of field symbol. to the metod set_table_for_first display, for further reference please check the sapmle code below.
type-pools: slis.
field-symbols: <dyn_table> type standard table,
<dyn_wa>.
data: alv_fldcat type slis_t_fieldcat_alv,
it_fldcat type lvc_t_fcat.
selection-screen begin of block b1 with frame title text-001.
parameters: p_flds(5) type c.
selection-screen end of block b1.
start-of-selection.
