I've been able to install version 1.90 of Koha, but after checking my MARC structure I received the following message from Koha: ====================== itemnum The field itemnum MUST be mapped The correspounding subfield MUST be in with -1 (ignore) tab the items.homebranch field MUST : homebranch NOT mapped be mapped to a MARC subfield, the correspounding subfield MUST have authorised value=branches the items.holdingbranch field MUST : holdingbranch NOT mapped be mapped to a MARC subfield, the correspounding subfield MUST have authorised value=branches TOTAL You have 3 error(s) in your MARC configuration. Please fix them before using koha ======================= Can someone please assist me in resolving this issue. OS = Redhat 7.3 (all patches) Koha = 1.90 (all modules installed properly) and sample database Any help would be appreciated. Patrick Logan Winnipeg School Division Manitoba, Canada plogan@wsd1.org
