Disclaimer: never done this from Python, but lots and lots of BatchCat work.
I believe you're missing the CatLocationID parameter - at least, your
example code has only 6 parameters but should have 7:
* RecordID
* MARCRecord
* DateTime (of update/creation)
* CatLocationID
* RelatedRecordID (the bib id from 004)
* HoldLocationID
* OpacSuppress
(source: BatchCat 9.0 PDF)
CatLocationID is the "cataloging location", which can be seen in the Cat
client on the History tab. It's the location used by editors when they log
into the Cat client, though it has little or no actual functionality -
basically just shows that some operator from the Main or Medical or History
library did that particular edit.
At UCLA, we have a systems-office location which I use in all of the
batchcat programs I write. Makes it easy to filter out "my" batch edits
from reports, and reassures catalogers that I (or my programs) am
responsible for all those edits they don't remember making....
If "459" really is your cataloging location (parameter 4), then you're
missing the HoldLocationID (parameter 6), which should be the numerical id
corresponding to what's in your 852 $b.
Hope this helps!
