Comment Line Product
In respect to the Comment Line and/or Meter Charge Comment Line on a Meter charge invoice the set up process is as follows:
Create a product to Stand for either one. There is already a standard product called 'Comment' with a product type = Comment
Ensure that this product is in the right non stock product category.
If you want the $0.00 to print on the meter charge shipment and Invoice, assign the product type = Comment, if you do not want to print a $0.00 on a comment line assign the product type = Meter charge Comment
If you have your own customized meter charge invoices, you will need to amend the layout to not print the $0.00 on the comment line.
There is a system reference code, Type = Sales, Code = 'Meter-charge-run-comment-line-template' in Administration>Advanced>System Types. This is used to format the meter charge run sale shipment/invoice comment line notes that print. The value in this code can be changed and saved.
