Hi Pamarthi,
You can choose timestamp field as numeric delta pointer while creation of Datasource. It will not throw error, but It will give error when using lower safety intervals in some cases.
Let's make some scenario to understand this:
Current time stamp is '20150921075855' (assumption)
- If lower safety interval is 100 secs
- So delta pointer will set on '20150921075855' - 100 = '20150921075755' @ RSA7, Next delta will work fine.
- If lower safety interval is 60 secs
- So delta pointer will set on '20150921075855' - 60 = '20150921075795' @ RSA7, it will throw error because it is wrong timestamp value and can not be set as delta pointer
So choosing timestamp field as numeric pointer based delta along with safety interval will not be correct choice.
Thanks,
