Symptoms

When importing a project into JIRA, the message "Custom Field <name> has multiple configuration schemes. Importer is unable to extend custom field context automatically." appears, with a warning that the import was incomplete. The following appears in the atlassian-jira.log:

2013-04-19 10:52:26,495 JiraTaskExectionThread-13 WARN username 652x369343x1 kgr84o 127.0.0.1 /secure/admin/views/ImporterLogsPage!import.jspa [imports.importer.impl.DefaultJiraDataImporter$1Thread[http-8080-22,5,main]] Custom field 'Rework Reason' has multiple configuration schemes. Importer is unable to extend custom field context automatically.

Diagnosis

This occurs in the situation where a CSV or other import attempts to add data to a Custom field A for issueType B and all following conditions are met: 

• Custom field A has multiple Custom Field Configuration schemes
• Custom field A has specific list of issues types (not 'Global (all issues)' )
• Custom field A has no context which are applicable to Project and IssueType B.

Cause

If the issueType is not part of the context of this custom field, then the field data cannot be saved.

Resolution

• Main step: Add issueType B into one of a Custom field A context.

• Optional steps: If don't specify issueType during import, make sure that default project issueType has a valid context. Or make sure that issueType column is present and set:
  • Add an issueType column
  • Add an issueType in this column for every issue (if you're importing to existing issues, this should match the issues' current issueTypes)
• Retry import
