Hello! I am using Access 2010 to link to a SharePoint 2010 list and update the list data using update queries. The SharePoint list is very large, over 17000 rows. Sometimes, the update query will fail with the error "Could not find field." No error number or field name in question is provided. What makes the issue very troubling is that it is intermittent with no obvious reason. Some records will be updated successfully before the error is thrown, so it can't really be a missing or misspelled field name in the query. I have reviewed the existing SharePoint data to ensure the values are not in conflict with field requirements, like choice field values and required fields. I am able to update the same record manually in the SharePoint list with the same update the query would have made, so I don't think it is a validation error. Any help would be greatly appreciated. This issue is getting worse and happening more frequently, causing me to not be able to complete the weekly updates. Thank you!!
