Hi Alicia,

The original problem of the import feature being broken for a dataset with a large number of fields has been fixed in LabKey versions 14.1 and 14.2. We have sent a LabKey 14.1 installer to your LabKey Server Builds page on your support portal. Please install the build and test on your development server and let us know if you have questions about the install process. Also note that the fix involves disabling import 'merge' into a dataset; insert is supported instead. What this means is that existing key (subject IDs / Date) values cannot be in the excel file being imported because this will cause a conflict and produce an error. Insert only works if those dataset rows have first been deleted. If you have questions or concerns about this behavior, let us know and we can discuss them.

Regarding your question on MVIndicator being exported, we will need to investigate further before responding.

Greg
