Printing an Invoice

Introduction

You probably know that, if you create a button on a form and call a report, when you click the button, all records on the report would be printed. On a data entry form, you may want to print only the report related to the record you are viewing. This is equivalent to printing an invoice. Although this involves writing code, only a very slight modification is necessary to implement this behavior. It consists of setting the criteria of the DoCmd.OpenReport method.
