[Koha] Mapping to Koha Full call number field

Hi all Our old system used to keep the call number in one field 852 with 3 sub-fields as follows: 852h - Classification part 852i - Item part and 852k - Call number prefix Now, Koha keeps the call number in 952o and so when importing records from the previous system, I mapped all theses fields into 952o and now the opac presents the call number in this way - 2806 POT LB instead of LB2806 POT. How do I fix this problem. Ephraim ---------------------------------------------------------------- This message was sent using IMP, the Internet Messaging Program.
