Error when changing Name from Text to AutoNumber

Getting this error when changing I try to change the Name field from Text to AutoNumber.

 

Error: Cannot change Record Name type to autonumber; field update exists.

 

Any Ideas? Thanks in advance.

I would guess you have a workflow field update action that's updating the name, which it can't do if its changed to an autonumber field.

Thats it!! Thanks.

 

Guess deactivating the Workflow is not enough. You have to delete the field update.

I get the same error despite deactivating and deleting the workflow rule. Any Idea please?

I had this issue as well. I deleted the field update from the WFR but that just deletes the link between the WFR and the field update so I was still getting the error. Go to Setup>Field Updates and find the Field Update and delete it from there.

DeActivate the Workflow rule and also delete the field update used in the work flow for the particular field. Now we can change the data type to Auto Number
