SNAP table contents

Hi Guys,

I was recently going through the snap table entries. It has around 150,000 entries which are less than 28 days old. But if that was the case it adds about 5000 dumps on an average every day. In our system in ST22 , we have a maximum of 50-100 dumps a day. Can you please let me know what all entries are stored in SNAP table. Are SM21 dumps also stored here?

Regards
