Hi Garry,
In Adagio Invoices, you have the ability of assigning items to different 'Styles'. This is because the details you can include on an invoice may require different information to print (ie stock items versus labour charges). Each item is assigned and grouped by one of up to 26 possible styles, that you define as a user.
What this means for your invoice and credit note specifications is that each detail section must be included for each style of item you want to print. For example, style A could represent stock items, so you would include qty ordered, qty shipped, unit price and extended price. Style B could be for labour charges, so you would label the fields as hours, rate, and extended price. You can see the flexibility this can provide.
In our sample specifications, such as the one you referenced, there are a number of detail sections that appear reasonable identical. Note that they are detail sections assigned to different Styles. There are also a number of text lines that are 'Suppressed if blank', a feature in all Adagio specification designers to eliminate unwanted blank space.
Regards,
