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.
<ErrorDetails xmlns:d2p1=”http://schemas.datacontract.org/2004/07/System.Collections.Generic” />
<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
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
