Excise Invoice for non valuated material

hii all,

please help me to capture and post Excise Invoice against Non-valuated material.

actaully, m recieving the material with 501E MVT type. my materials are non vauated (mat- type : UNBW).

m trying to capture EI with J1IEX (caputer EI w.r.t without purchase Order). then m getting the message that " DOCUMENT DOES NOT CONTAIN ANY ITEMS".

thanks
