If I am importing a lookup ID, last name, and System record ID into a Constituent Update Batch, then it would be helpful if constituent type was not also required. Right now, if the value of constituent type does not match the defaulted value, the system will recognize that and spit out an error that "record type cannot be changed." Unfortunately, this cannot be dismissed or edited in batch, When this occurs, the only thing we've been able to do is start over and import the data with a value record type. There has to be an easier way to work through this.
