When using an import file that uses an enhanced revenue batch template and constituents are matched to existing constituents certain constituents will display an error CK_CONSTITUENCY_DATETODATEAFERFROM. When navigating to the constituent record there are constituencies that have either a missing 'date to' or 'date from' beside a constituency and the error can be removed from batch by entering a date in these fields
We are currently evaluating this issue for a fix in a future release.
Workaround: 1. Open the Constituent record and locate the Constituency 2. Add a Date From to any constituencies that do not already have a date from but has a Date To 3. Re-validate and commit the batch
