I'm using MS CRM 2013 On-Pre, In the Trace file i found below line in error message attribute when trying to delete any field or entity even when trying to add new entity or field.In sort at this time I am not able to do any changes in my CRM.
"Microsoft Dynamics CRM has experienced an error. Reference number for administrators or support: #0494EF01"
How can I analyze the code, Is there any entity where I can find all the error code.
Please suggest I'm totally confused.
@BharatPrajapati alex is right, you probably broke the environment.
One should never change fields and Entities directly in SQL. This is highly un-supported Customizations.
If you had setup daily backups for the CRM Database. You can restore the backup on the same CRM Organization. It will start working fine. You have to map the security roles etc again.
If you want to delete the the Entity which you deleted from SQL you can/should delete that in CRM
P.S if you do not have daily backups schedule then there is no solution other than a New CRM Installation.
