Invoice lastModified / Closed status

[CoreDnaDev]

Hi,

I am trying to find list of invoice having any changes made last period of time. (ex 10 minutes)

For example, if the `Comment` is updated my api, an api query picks up this invoice from MYOB, and I can use this invoice record for next jobs. But I have found that when `Status` is updated from Open to Closed, LastModified time stays as it is. (Status is updated by making Payment)

Is it a bug or any purpose of setting up like this? And.. any easy way to find list of invoices updated last 10 minutes for example?

Thank you
