It is possible to change an item type's field that is already in use by using the Roundtrip export
To start, you need to create a new data field. Go to Admin > Item Types >
Select the item type > Config > Add Field
to create the new field.
Note that the new field should be of a new type. This will allow you to change the field type, by replacement.
You also need to take into consideration the type of data you have when changing the field type. For instance, text content cannot be stored in an Integer as an Integer can store only numbers.
After creating the new field, you need to add it to the List View
so it can be exported. You can do this through the Admin > Item Type > Configure View
option, by adding the field to the list on the right.
Alternatively, you can use the Configure View
option in the List View
to do that.
Locate the items you want to change by creating a filter or opening their set in List View. From the List View, open the Export
Menu > Office Templates
Select and Run
the Excel Export for Roundtrip
This will generate an Excel export. Open the export in Excel and copy and paste the data from the old field's column to the new field's column.
You can now save the spreadsheet and import it back into Jama Software.
Also, don't forget to check the box for round-trip
The items will be updated in that Project, though this needs to be done in every project that uses that particular item type.
If the new field type is compatible with the data imported, you should be able to see identical data in the two field types (otherwise, the new field will be empty).
After you confirm that the data was successfully imported to the new field type, you just need to go to Admin > Item Types > Config
again and delete the old field
to complete the change.#administration
