Three changes, one feature: a period with no baseline borrows a shape from
prior year or plan.
The generator handled one date group. sql_generator.js used find(), so a
source with order, requested and ship date groups derived the order one and
copied the other two raw -- shifted dates against unshifted period labels.
Every group now gets its own join, and they are LEFT rather than inner: an
order that has not shipped has no ship date, and an inner join would have
dropped the row from the load entirely rather than leaving its period
columns empty. dateGroupsOf() is now shared, like grainOf, so the routes and
the generator agree on membership and on join aliases.
Clone carries every date column rather than only the primary one, since it
is the operation that moves rows through time, and re-derives the period
dimensions from pf.dim_period against the shifted date instead of copying
them from the row being cloned.
from_logid names the segment to copy from, replacing the exclude clause for
that one entry rather than widening it. Rows written stay pf_iter = 'clone',
so scale applies to them afterwards as a second step.
set is no longer required: copying a segment forward unchanged is a
reasonable thing to ask for.
Needs dim_period_col set in Setup (fisc_year on oseas/rseas/sseas_e,
fisc_month_abbr on omon/rmon/smon_e) and Generate SQL.
