Qualify data based on non-class property

Hello Group,

Can we qualify data based on non-class property? Using following mechanism, I was receiving error as shown here:

EOKeyValueQualifier custQual = new EOKeyValueQualifier("custID", EOQualifier.QualifierOperatorNotEqual, sales.toCust());

NSArray activeCusts = EOQualifier.filteredArrayWithQualifier(sales, finalQual);

com.webobjects.foundation.NSKeyValueCoding$UnknownKeyException: <com.mtj.model.Map 0xcb43d9> valueForKey(): lookup of unknown key: 'custID'.

This class does not have an instance variable of the name custID or _custID, nor a method of the name custID, _custID, getCustID, or _ getCustID
