I'm using the SharePoint List Adapter in SQL 2012 SSIS to import a large list > 5000 items. I receive this error: "Microsoft.Samples.SqlServer.SSIS.SharePointUtility.SharePointUnhandledException: Unspecified SharePoint Error. A possible reason might be you are trying to retrieve too many items at a time (Batch size)"
I have tried different batch sizes. Its currently down to 100 and I only have 8 - 10 columns. As a test, I set up a filtered view on an index column on the same list and was able to import all 2000 rows from that view without issue.
Is there something special I need to do to import a large list? I can manually do it now in batches by adjusting my view but there must be a better way.
