read data from maintenance view

hi all,

could anyone please tell me if there is any special way to read data from a maintenance view (if at all it is possible).

i wrote a simple select on it but it gave me a syntax error that the view is not defined in the dictionary. (i am able to see the view definition by double clicking and it is active too).

the following is my select.

select single lgnum from v_t320 into (w_lgnum) where werks eq p_i_werks and lgort eq p_i_lgort.

awaiting answers...

regards,

PJ
