SYSERR229

SYSERR229|The EXECUTE permission was denied on the object ‘IdList’

Recently I ran into this error while validating a model on a new instance. I checked the SQL accounts that MDS is running under and one of them was incorrect. The ‘mds_schema_user’ no longer had lost access to the ‘mdm’ schema. I granted the account ownership of the schema the model was able to validate normally.
