We are trying to begin to use KOHA. Now we are working with MARC structure. When we run "MARC CHECK" we got the following errors: ----------- itemnum The field itemnum MUST be mapped The correspounding subfield MUST be in with -1 (ignore) tab itemtype NOT mapped the biblioitems.itemtype field MUST : be mapped to a MARC subfield, the correspounding subfield MUST have authorised_value="itemtype" homebranch NOT mapped the items.homebranch field MUST : be mapped to a MARC subfield, the correspounding subfield MUST have authorised value="branches" holdingbranch NOT mapped the items.holdingbranch field MUST : be mapped to a MARC subfield, the correspounding subfield MUST have authorised value="branches" ------------- We would appreciate whether some one can help us informing where to fit these errors. Thanks H. Botero
