We have a string tag that contains the batch Id. We want to use this tag as the Active ID for creating batch events in event frames generator. However, when I checked the archive editor to see the values for this tag, I found out that sometimes there is no value against some timestamps. So, when i use this tag for generating batch events, it creates a batch with <Blank> as the event name. Any idea how to avoid creating this <Blank> batch. Also, any pointers on why the archive contains such timestamps where there is no value?
