Pankaj,
I am not clear what exactly you are doing in your code. I think you have assigned to different variables to the same field symbol. So, only the latest one will be present.
L_DATA = C_BKPFZZBUNIT_SRC.
ASSIGN (L_data) TO <fs_bkpf>.
assign EX_BKPF-zzbunit_src to <fs_bkpf>.
Here you have assigned L_DATA and also EX_BKPF-zzbunit_src to the same variable. So, now <fs_bkpf> will have the address of EX_BKPF-zzbunit_src.
L_DATA = C_BKPFZZBUNIT_SRC.
ASSIGN (L_data) TO <fs_bkpf>.
Once this is done, directly assign the value to <fs_bkpf>.
<fs_bpkf> = '100'.
This should update the variable.
If NOT please explain the coding once.

Ravi
