Trying webservice with object BOD and field BOMALT

SOLVED

Hi all, when i try to create a new BOMP with Web Services it always return me this error "BOM code : 1\Record does not exist" on Field error [M:BOH0]BOMALT and i am sure that code "1" exist on my Sage X3 v9 (patch 6).

this is my xml so far: 

<PARAM>
<GRP ID="BOH0_1">
<FLD NAME="ITMREF">2OALBR001106</FLD>
<FLD NAME="STOFCY">ITS02</FLD>
<FLD NAME="BOMALTTYP">2</FLD>
<FLD NAME="BOMALT">1</FLD>
</GRP>
</PARAM>

What am i doing wrong?
