Completes the AP source layer: GP was covered by the pm* modules, but the
CMS side had only cms.vend. These three are what
SQL/fiscal/analysis/open_ap_aging.db2.sql actually joins.
avtx 966,553 A/P voucher transaction events incremental on AVTSTM
vchr 792,348 vouchers entered, period to date full
open 538,544 open payables; FHCBAL is live full
AVTX is the artrn analog -- the per-event apply detail. It matters
because the AR aging in /opt/clean reconstructs balances from
application events rather than a single settle_date, so AP needs an
applications fact too, not just documents.
Grains verified exactly unique before drafting: AVTX
(avtco#,avtvh#,avttx#) 966,553/966,553; VCHR
(idcom#,idvch#,idbnk#,idfisy,idfisp) 792,348/792,348; OPEN
(fhcom#,fhvch#,fhpyy,fhpper) 538,544/538,544. All three reconcile
IN SYNC.
vchr and open stay full: no change signal, only business dates, and
FHCBAL is a live mutable balance.
Two things worth knowing for the next DB2 module:
- pipekit maps DB2 TIMESTMP to Postgres text, so a watermark resolver
doing COALESCE(MAX(ts), TIMESTAMP '...') fails on mismatched types.
Cast explicitly. cms.gtran was already the precedent.
- Watermarks resolve at engine step 2 but --create-dest builds the
table at step 3b, so a watermark reading its own dest table fails on
the first run. Pre-create the table or seed with a constant.
Note LGDAT.AP* is a dead end -- APVH has 14 rows, APVD has 22. CMS AP
does not live in AP-prefixed files.
