How to remove repeating group instances in Vantage?

Answer

The Remove() method can be used to remove the instances of the repeating group. The script sample is the following:

var document = Context.Transaction.Documents[0]; 
var field = document.GetField("Invoice Date"); 
if (field.Value != ""){ 
    for (var i = 0; i < field.Instances.length;){ 
        field.Instances[i].Remove(); 
} 
}
