Invoice printing with Crystal report

SUGGESTED

I have a client on Sage 50 2013 that prefers a custom Invoice form which I cannot customize with the current forms.

I have created a Crystal report, but I cannot find where the Sales Rep from the Invoice is save in either the JrnlHDR or JrnlROW.

Does anyone know how I can get this information?  I know it defaults from the customer, but if is it changed on the Invoice, I want the correct sales rep.

Thank you in advance.
