How to Resolve SQL Server Error on a Microsoft CRM 2015 Rollup field Delete

I had encountered the following SQL Server Error when trying to delete a Microsoft Dynamics CRM 2015 rollup field.  This is deleting the actual rollup field from the entity and not simply removing the field from a form or view – also it is cleared of any dependency.image

<ErrorDetails xmlns:d2p1=”” />
<Message>System.Web.HttpUnhandledException: Microsoft Dynamics CRM has experienced an error. Reference number for administrators or support: #DFcA6B5C</Message>


How to Resolve:

  • Open the rollup field definition


  • Change the Rollup Field’s Aggregation field to another field


  • Save and Close
  • Delete
    Note: After the Delete is done – the Field definition still display.  OK to close it and if you refresh the list of fields – this rollup field is deleted
