Overwriting existing timestamp in summary index?

[yuwtennis]

Hi!

Is it possible to overwrite the summary index with same timestamp?

Lets say you already have a summary index as following.

_time fieldA fieldB
2014/1/1 00:00 a b
2014/1/2 00:00 a b
2014/1/3 00:00 a b

I want to rewrite the first record to recalculate the value as c
_time fieldA fieldB
2014/1/1 00:00 a c
2014/1/2 00:00 a b
2014/1/3 00:00 a b

Do you have to use the delete and then repopulate it?

Thanks,
Yu

Yes, you will have to repopulate it - you cannot change any data in an index once it's been written.

Hello ayn.

Thank you for the comment.
Is there be a way to detect the duplicates and delete the old ones?

Thanks,
Yu
