If you are running Act! with a 3rd party reporting tool like TopLine Dash , Crystal Clear Essentials or Durkin ImpactSuite; then, you may run into a problem with this field missing from the field selector.
The problem is the in OLDEB provider. The OLDEB provider is a bridge for Act! report writers to see the tables and relationships in Act!. For reasons unknown, when Act! is upgraded from v15+, the OLEDB provider doesn’t add this field to the provider.
The solution is to download this fix and run it on the server that hosts Act!, and you must have full administrator rights to install this patch. Restart your reporting application, and you should see this work.
