The supplied Workflow Time is more than 3 periods after the last import period

We are currently in the process of upgrading to OFC  PV840-SV112 and just applied the upgrade to our Customer Acceptance Testing Application where we have our imports and matching running daily.  However, the amount of data imported is much less in this applicationas it is using a test database to import the data from and one of the matchsets has not imported any data for many months.

The matching step for that matchset erred out a couple of days after the upgrade with the message "The supplied Workflow Time is more than 3 periods after the last import period".  We discovered that if we loaded just one "dummy" row for the matchset that the error stopped happening.

My questions are - has anyone else noticed this?   And, if so, is there a setting somewhere to either turn this check on or off or increase the number of months that it looks back?

Thanks for any information you can provide.
