I'm new to sage, so this may be obvious but I can't find out how to do this.
I have created a customer, and when I invoice them I have to include my "supplier reference" they give me on all invoices etc. This reference is longer than the reference field used within Sage to reference the customer themselves. I could put this into a custom field, but how do I get that printed on the invoices etc.? I tried to use the report designer to add the custom field, but it just added the text of the renamed custom field, not the data that was entered into the custom field itself.
