There are a few reasons your dataset may not be saving. First, check to see if you have given a name to your dataset. If the dataset does not have a name it will not save.
Next, check is to see if you set a Unique Primary Key. If you do not have a unique Primary Key Field set, it will not allow you to save the dataset.
