Trying to update Associate details (resigning a director/PO and adding a director/PO) on the ABR portal and keep getting this error: The effective date of change is prior to the last given start date. please use a date that is later - an error code is 20001.
These are the first changes I'm updating for this entity, so unsure why I'm getting this error. This is a common error and there's no clear explanation as to how to fix it. Hoping someone can assist or provide guidance that doesn't involve phoning (as I obviously can't update PO over the phone). thanks.
