If Keyword Values in Keyword Type Groups are not being saved to scanned documents, then a client-side Scan Acquisition Server file may be causing a version conflict. Ensure the client-side files match the version of OnBase you are using.
The client-side Scan Acquisition Server files are OnBase version-specific. Check the files' versions to determine whether they are compatible with your OnBase version.
Note:
The file obepicscanwrpXx.dll is not version-specific. This file can still be used with multiple versions of OnBase.
