 +The data set can also be looped programmatically by scripting as follows:
 +   dataset = $SYS.getDataSet('PaymentOptions');
 +   
 +   // rewind dataset to first row
 +   dataset.rewind();
 +

 +   rowIdx = dataset.nextRow();
  
 +Please note that the data set being looped programmatically as above can not be attached to the transition at the same time.
