The question mark wildcard allows you to restrict a report even further than the asterisk. Use the question mark to limit your report to elements that contain only a specific number of characters.
For example, say you want to print a Job Transactions report for the Cadwell Corporation. All Cadwell job numbers are three characters long and begin with the letter C. However, you have other jobs that start with the letter C and you don't want those jobs to appear on the report. In the Selected field of the Job Transactions report's Report Customization window, enter C?? to limit the report to three-character jobs that begin with C.
Like the asterisk wildcard, the question mark also can be used in other locations in account, item, purchase, sale and card names.
