Hi,
I don't know whether you require the custom container. Try the below code(I have removed the custom container section) and see if the error persists:
DATA: gr_data Type Ref To DATA.
DATA: la_data Type Ref To data.
FIELD-SYMBOLS: <gt_data> TYPE STANDARD TABLE.
my Full source code.
me->get_data( CHANGING c_data = <f_tab> ).
METHOD get_data.
GET REFERENCE OF c_data INTO la_data.
move la_data TO gr_data. " pass to global variable
assign gr_data->* to <gt_data>.
if table is not bound.
try.
"// Create ALV Instance
cl_salv_table=>factory(
importing
r_salv_table = table
changing
t_table = <gt_data>
).
catch cx_salv_msg. "#EC NO_HANDLER
endtry.
"// Setup ALV Attributes
functions = table->get_functions( ).
functions->set_all( abap_true ).
columns = table->get_columns( ).
columns->set_optimize( abap_true ).
try.
column = columns->get_column( 'MANDT' ).
column->set_technical( if_salv_c_bool_sap=>true ).
catch cx_salv_not_found. "#EC NO_HANDLER
endtry.
"// Dispalay ALV Model
table->display( ).
else.
table->refresh( ).
endif.
ENDMETHOD
If you want to use a custom container, u need to create a screen(say 9000 in SE51) for your program and create the custom container in it. U need to call this screen in your program for the ALV output. You can use PBO and PAI of the created screen for ALV display and coding user command section.
