  • I am unable to export more than 2000 records to excel from SharePoint external list. External list has 5000 records but only 2000 records getting exported to excel.

    Any help on this would be highly appreciated.

    Thanks in advance.

    • This is because of the throttling limit on External List. Use Set-SPBusinessDataCatalogThrottleConfig to increase the limit.

  • Any one else experience frustration while converting a solution package to a sandboxed solution package. It’s been quite a challenge for me because I have to look for work arounds to doing things like adding a web part to a page, programmatically adding an event receiver, and programattically editing the properties of a field.
