  hasbeenpaid: 'N'
}, function(pendingOrderList, me) {
  // success
}, function(tx, error) {
  // error
}, this);

Searching business partners:

/* rest of the code */
var criteria = {};
if (filter && filter !== '') { // filter is a parameter of the function
  criteria._identifier = {
    operator: OB.Dal.CONTAINS,
    value: filter
  };
}
 
OB.Dal.find(OB.Model.BusinessPartner, criteria, successCallbackBPs, errorCallback); // success and error callbacks are previously defined
