Problem: Error Message – Cannot Perform This Operation on a Closed Dataset


Solution: When this happens, the user is most often trying to create a new sale, though not always.

The most likely culprit is one or more empty response files.

To confirm this, with DataLog closed, go to the drive (usually C) where the following is found:

(My)Documents\My UAAR\My Sales\.Configuration Files

Search for files with 0 kb size and delete them.

Reopen DataLog and create a new sale to ensure that DataLog works properly.
