You're entering records into a database, and you realize you don't have the information for one of the fields. What do you do?
Use letters in alphabetical order to select options
In the Field Properties section, change the Required field to Blank so users can skip the field during data entry.
Unless a field's set up to require an entry, you can skip the fields for which you don't have any data.
In order for a user to leave a field blank, you'd have to set its data type to Optional so that data entry personnel can skip it.
Access doesn't allow blank fields, so you have to wait until you have all the fields' data before you can enter that record.
