After the first read, BATCHJOBHISTORY was read from the watermark minus an
overlap of 2000 RecIds with TOP (1000), oldest first. From AX 4.0 RecIds are
handed out per table and are dense, so once 1000 rows existed in the overlap
every read returned the same old rows: the watermark never moved and new runs
were never read again (every AX 2009/2012 installation with more than ~1000
history rows). The read after the watermark now takes the overlap plus 1000
rows (TOP (3000)), so at least 1000 new runs are read each time. Test with
20,000 dense RecIds.
