You got it. Mercator always creates output "straight down the page" (No
DO...LOOP or FOR..NEXT or IF.. GO TO) so whenever you need
one output per input with a variable number of inputs you need a functional map.
No other way.
Here's a tip for your ASN map: use a passed INDEX($) to each level of functional
map to control your HL01 numbering; you will also
find it handy to pass a 'parent HL01' value as a parameter as well. Depending on
how deep you have to nest the HL loops, passing
these as parameters instead of using COUNT() all the time will speed up your
map.
Of course, you could always engage a qualified Mercator consultant to do that
'first' ASN for you, and then use that as a guide for
future ASNs (or other deeply-nested outbound documents).
But realistically I've found the bigger problem is getting the input defined
correctly: the type tree for the application interface
file needs to be set up with the 'occurs' in synch with the output requirements.
That all by itself may require a separate
functional map.
