[Koha] catalogin, dewey, and marc-to-koha mapping

[Darla Grediagin]

This is what I am working on today so I thought I would chime in with a 
question.

I am looking for the itemnum.

This is the error I get with the marc Check
    * The field itemnum MUST be mapped
    * The correspounding subfield MUST be in with -1 (ignore) tab

I have spend an hour looking for itemnum.  Is this the same as the barcode?

Thanks in advance,

Darla

> Originally we imported records from Athena.  Athena uses tag 952, subfields k,h,i,m (k=Call number prefix, h=Classification part, i=Item part,m=Call number suffix).  We mapped (Koha tag 952, subfield o) to (Athena tag 852, concatenation of subfields k,h,i,m).  We used this script:http://contribs.koha.org/revision_view.php?rid=15.  (Note: I created this script and uploaed it to contribs.koha.org.  If the script doesn't map the fields correctly I need to fix it before my mistakes cause problems for others.)
