Slide
notes: This is an example of an Invoice. On this Invoice, we use a UNIT to
display the Line Items on the Invoice, and in the Unit, we use the 'Numeric
Iteration' Template for some of the Values.
Slide 2
Slide
notes: The Quantity, Amount & Tax columns all use this kind of
Template.

Slide
notes: We note also that this type of Unit Call is based on a Data Source,
and for this type of Unit the Data Source is often'docwritespre', i.e. with a pre-prepared
record specifically for the Report.

Slide
notes: From the Metadata, we can retrieve the Data Source Layout.
Slide 18
Slide
notes: We will connect the Tags back to this Layout, to understand where we
get the answers from.

Slide 23
Slide
notes: This is our Unit example for this Report. In fact, even the Date
column uses the 'Numeric Iteration' Template.
Slide 24
Slide
notes: Of course, the Date in this case is available in internal format,
i.e. a number, and we can see at the Display Mask field that we use a
Display Mask to turn it into a Date presentation.
Slide 25
Slide
notes: And the actual Data that is used for the answer is of course an
iterative Value from field number 1.
Slide 26
Slide
notes:
Slide 27
Slide
notes: And in the Data Layout for the Transaction Lines, we can see that
the Date is available from Field number 1.
Slide 28
Slide
notes:
Slide 29
Slide
notes: Let's look at the Amount example.
Slide 30
Slide
notes:
Slide 31
Slide
notes: For the Amount, we also use a Display Mask, and this time a type
that we commonly use for Financial Values.
Slide 32
Slide
notes: The answer comes from Data Field number 5.
Slide 33
Slide
notes: We can see this in the Data Layout also.
Slide 34
Slide
notes:
Slide 35
Slide
notes: And with all of these Templates, we accumulate the Iteration Value
into an Accumulator, so that if we need a Total for the Column on the
Report then we can get it from the Accumulator.
Slide 36
Slide
notes: This Template is ALWAYS used with a Data Source Record where the
Unit is based on an included Data Set where a number of Fields have
correlated multi or iterative Values.
