If you do not wish to edit schema.xml directly, you can use the Schema Editor in the AccuRev Java GUI. Identify an existing key field that can be used, or define a new one using the
Add button. Then assign this key field using the
3pty ITS Key dropdown menu.

Note that some AccuRev schemas (like the schemas delivered with AccuSync) already have a third-party key defined, such as “jirakey”. If this is the third-party ITS key that you need to use, you just need to ensure that it is assigned to the
3pty ITS Key dropdown menu as described above, and that it is positioned on the Issue form as described below.
Next go to the Layout tab and position this field in the Issue form (or confirm that it is already there). To position it, select the entry in the Fields column, and then click where you want it to appear in the left side of the tab (for example, in the Header section).

Do not use this for third-party ITS keys. Define a new one (or determine if you already have one available in your schema) and make sure that it is specified in the
lookupField as described below.
After identifying a key field, or defining a new one, modify the fid value of the
lookupField entry to reflect the new key field (the
lookupField entry is typically found near the top of schema.xml:
For example, if you were modifying this entry to use the jiraKey field shown above, you would change the
fid value to “3”.
To position this field on the Issue form (or to confirm that its position is already defined), open layout.xml in a text editor. Use the existing entries in the file as a model for defining the third-party ITS key field.
