Michelle Leonard Dummy Employer Identifier We have an employer who is waiting for an EDRN to be generated. I was under the impression we could use the dummy "999999999" (See below). However, I am getting an error on the rule violation report saying The Employer identifier is not valid? Can anyone shed any light please? A value of 999999999 can be used temporarily (within 60 days of the learning aim start date) until the employer number is known.
