Thanks,
This would work for a single iteration, but this search would need to be
performed multiple times (with different record IDs). An id is fed in,
the relevant records retrieved and processed, then the next id is fed
in, and so on.
It's after the loop has finished (i.e. all the expected record IDs have
been checked) that I need to be able to determine which records weren't
matched by any of the supplied record IDs.
