Oracle Fusione - Groovy Script insert row in a related collection

Hi, i need to insert a row with groovy in a related collection of object partner. I try with this code:

def vo3 = newView('PartnerProfileOrgPartyPVO');

def vc3 = vo3.createViewCriteria();

def vcRow3 = vc3.createRow();

def vc4 = vcRow3.ensureCriteriaItem("OrganizationName");

vc4.setOperator("=");

vc4.setValue('BIMRCO01');

vc3.insertRow(vcRow3);

vo3.appendViewCriteria(vc3);

vo3.executeQuery();

if (vo3.hasNext()) 

{

def row = vo3.next() 

def vo1 =row.LegameGerarchicoSuperiore_Legame_Tgt

def createRecord = vo1.createRow()

createRecord.setAttribute('RecordName','ASCXVX09')

createRecord.setAttribute('CodiceVenditore2_c','BIMRCO01')

createRecord.setAttribute('SkipTrigger_c','Y')

def defaultDate = date(2049, 12, 31);

createRecord.setAttribute('DataFineLegame_c',defaultDate)

vo1.insertRow(createRecord)

}

When the parent hasn't record in the collection the insert is ok, but if it has some records i have the error "RecordName is required" also if i use createRecord.setAttribute('RecordName','ASCXVX09').
