Gateway BATCH update operaton

Hi Gateway folks,

I had an issue while doing batch operation and I have below queries in my mind.

1)  if we have single entity type for batch operation then Changeset Begin will trigger based on number of PUT operations in changeset of batch operation and at finally it will trigger the Changeset End method

Eg : if we have 10 put operation in  batch then Changeset Begin method will trigger 10 times

2) In the same way if we have two different entity types in single batch operation ,how many times could Changeset Begin method will trigger?

3) how to capture the all ten times put operation values into Changeset End method at final execution

Thanks in advance!!!!

Thanks
