Hi,
I am trying to modify a standard program that will generate the list of notifications ( QM15) , Before displaying the list , i insert a small code to modify the g_fieldcat_tab & object_tab to add some more dynamic colunms( we do know the amount of cols to add , this depends on some condition) into object_tab but i can not do this , because object_tab is a fix internal table .
I tried to use CALL METHOD cl_alv_table_create=>create_dynamic_table but i did not succeed ,
please help me out of this
If possible please give me a small line of code for doing this
Thanks

Hi Hoa,
plz go thru this code, it may be help you.

Hi,
Here is a quick example.
report zrich_0001.
type-pools: slis.
field-symbols: <dyn_table> type standard table,
<dyn_wa>.
data: it_alvfc type slis_t_fieldcat_alv,

wa_fldcat type lvc_s_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.
build the dynamic internal table
perform build_dyn_itab.
write 5 records to the alv grid
do 5 times.
perform build_report.
enddo.
call the alv grid.
perform call_alv.
