Create the report as you normally would. Then from the screen that displays the individual record (i.e. Form) add a button to open the report. The wizard should prompt you if you want to limit the report based on the current record. If it doesn't you can manually add the where claus to the line of code that opens the report. To do this use the following syntax:
Docmd.OpenReport "ReportName", acViewPreview, , "[Primarykey] = " & Me.PrimaryKey
Substitute your report name and record id for the placeholders given.
