Read Only Field with out ability to update later
I'd like to modify a validation rule that would prevent a user from changing or deleting the contents of a field after data has been entered.
This formulat allows you to do just that but, if I create a record, with no data in the field, save it but return later to enter data into the field, the record errros out, not allowing me to save the record.
Does anyone know how I could modify this to allow users to create a record and if the field is left blank on save, can enter a value later? But if a user enters data into the field on create new, they should not be able to modify the field later. If they try to modify the field data or delete the field data and try to save it, it should error out.
Here is my number field type VR:
Thanks,
Nick

IF(ISNULL( PRIORVALUE( Quote_Number_P4__c )),FALSE,ISCHANGED( Quote_Number_P4__c ) )
