Summary 

When importing issues through a CSV file into Jira, on the field mapping screen, the user can't find a certain field to map because it is not shown on the drop-down list.

Example scenario

On the field mapping screen, the user can't map the field Issue Type because it is not shown on the drop-down list.

Environment

All versions of Jira Core 7.x, 8.x, 9.x, 10.x

Diagnosis

1. The expected field is not mapped in the Field Mapping step of CSV import.
2. When trying to manually create the record through Jira's "Create" button on the header, such fields are also not present in the creation screen.

Cause

A) The missing fields are not present in the respective Create Issue Screen for that issue type in that project.  For information related to assigning screens to specific operations such as the Create operation please see Associating a Screen with an Issue Operation.

B) The missing field has no context for the project and/or issue type. For more information on custom field context please see our documentation Configuring Custom Field Context

C) The field is one of the banned fields for bulk create issues:

• Attachment
• Created
• Creator
• Custom Fields
• Due Date
• Issue key
• Issue Links
• Issue Type
• Last Viewed
• Original Estimate
• Project description
• Project key
• Project name
• Project type
• Project url
• Resolution
• Resolved
• Security Level
• Status
• Time Spent
• Updated
• Watchers
• Worklog

 A and C happen only when importing using the Issues > Import Issues from CSV path. The fields should show up normally in Administration > System > External System Import > CSV.

D) If the CSV import file has two columns with the same title (this can happen for fields that accept multiple values), the importer screen will limit the fields available to only those that can accept multiple values (such as labels, affected versions, Components, etc)

Solution

A) Missing fields in create screen

1. Go into the respective project administration screen
2. Click on the project's Screen Scheme
3. For all affected issue types, edit their respective Create Issue Screen and add the missing fields

OR

1. Import the CSV using Administration > System > External System Import > CSV

B) Missing Field Context

1. Go to the context configuration page of the field in question
2. Add or edit the existing context to include the project and the issue type in question

C) Banned field

Request an admin to import the CSV or don't import those fields.

D) Duplicate columns in CSV file

You can either select a field that can accept multiple values, or alternatively, you could rename one of the columns in the CSV file before importing it in order to place that data into a different field.
