[Koha] Export of 773$w via OAI/PMH

[Uwe]

Hi,

I run into a strange problem and wonder if this is a configuration
problem or a bug in Koha. We are using Koha 24.11.02.

Wenn exporting all records with export_records.pl the field 773$w
shows up in the export whichever record has it set. When I get the latest
changes by OAI/PMH e.g.
'verb=ListRecords&from=2025-06-16T04:00:00Z&until=2025-06-16T10:00:00Z&metadataPrefix=marcxml'
none of the records has 773$w set, though it should be set. Other
subfields of 773 (773$t and 773$x) are exported. Just 773$w is missing.
Is there any explaination for it?

  Uwe
