TGIF Brainteaser - April 12

Thank God it's Friday!  OK, I missed Friday by a couple days, but who doesn't like a good Jet Reports challenge?

As I was riding the bus back to Bristol after an onsite in London, I was appreciating the fact that when it comes to Jet Reports, often times there are more than a couple ways of getting the job done.  The true test of a good Jet consultant is not only the ability to build reports, but also to analyze reports and identify how it could have been done more efficiently or understand when it will fall apart.  The good news is that the Direct to SQL connector for on premise NAV installs eliminates a lot of need for optimization!

But anyway, without further ado I present, the TGIF challenge: Item Sales by Customer.

For Sales Analysis purposes I need a report that shows all items sold on an Invoice Line or returned on a Credit Memo line grouped by the Customer.  If a customer bought and returned an item, I don't want to see the item twice.

In other words, In my report, I want to see all unique combinations of Sell-To Customer No. and No. for Sales Invoice and Credit Memo Lines. 

The challenge criteria are:

• Only use any combination of the following tables: Customer, Item, Sales Invoice Line and Sales Cr.Memo Line.
• Do not rely on Conditional Hide to hide rows without data.
• Only use up to 3 NL() functions to aid replication.  Use any number of GL(), NF(), or NP() functions.  Note: The NL("SUM")'s for "Num Credited" and "Num Invoiced" don't count.

Lastly for those of you pursuing JCT or JCP certifications:
Ignoring the challenge criteria opens up several ways to build this report.  Assuming the report will consume several thousand records, identify the methods which might produce a more efficient report in NAV 2009, NAV 2013 On Premise versus Cloud.
