I have just installed Koha 2.2.7. However after defining the MARC structure and doing a MARC check, I got the following error.

OK itemnum : the field itemnumber is mapped to a field in tab -1
item fields ALL items fields MUST :
  • be mapped to the same tag,
  • and they must all be in the 10 (items) tab
OK Only 1 MARC tag mapped to items
OK biblioitems.itemtype defined
OK itemtypes defined
OK homebranch defined
OK holdingbranch defined
OK biblionumber and biblioitemnumber mapped correctly
OK no NULL value in frameworkcode
TOTAL You have 1 error(s) in your MARC configuration. Please fix them before using Koha



Has somebody come across the same error and how can it be resolved.
