Timing Constraint problem on set_input_delay

Hello.

I have encountered problems on the following timing constraint.

The case is draw in the attachment.

I do timing constraint as follows.

creat_generated_clock -add -name {SysClk} -source [get_pins {*|inclk[0]}] [get_pins {*|clk[0]}]

set_input_delay -clock [get_clocks {SysClk}] -max tAO -reference_pin [get_ports {A[0]}] [get_ports {D

[*]}] -add_delay

set_input_delay -clock [get_clocks {SysClk}] -max tAO -reference_pin [get_ports {A[1]}] [get_ports {D

[*]}] -add_delay

set_input_delay -clock [get_clocks {SysClk}] -max tAO -reference_pin [get_ports {A[2]}] [get_ports {D

[*]}] -add_delay

set_input_delay -clock [get_clocks {SysClk}] -max tAO -reference_pin [get_ports {A[3]}] [get_ports {D

[*]}] -add_delay

But the timing constraint is ignored for the reason as said in the tool.

"Reference pin A[0] is invalid.it is not clocked by the clock specified in set_input_delay/set_out_delay's -clock options."

So,why the warning occurs?And how to do timing constraint at this case?
