Create the JV on a JV form
A JV template is included here, Journal Voucher Template - A form similar to this can be created in Excel for use in documenting JVs. Banner entry is then accomplished using the information on this form. The JV number is added when a Banner number is obtained. A copy of supporting documentation is attached to this form, and kept in the department.
You may use this format, or create a template of your own. A copy of all JVs created in your department should;be kept in the department with the documentation that justifies the JV attached.
