When I update my custom Record__c a trigger runs, and it calls recalculateFormulas() on the record. This results in the following error:

System.UnexpectedException: Unable to create/update fields: IsDeleted. Please check the security settings of this field and verify that it is read/write for your profile or permission set.

Same thing happens when I update Record__c inside a unit test. The object has several cross-object and non-cross-object formula fields.

Any ideas what's causing this error?

    Sounds like a possible bug....If it is I can't believe it made it out as that type should have been caught...(never would have worked)

    @Eric I'm seeing similar issues after using recalculateFormulas() for the first time today : Opportunity: bad field names on insert/update call: Account, Owner - the irony is that if I hadn't read this OP a few days ago, I wouldn't have known this new method has been added :-(

Are you trying to update IsDelete field from cose in trigger? If so can you just use delete dml on such objects where you want to set IsDelete as true.

  • That's an immutable system field..
