Hi @Kyung_Park,

In Import options, you can create a new calculated field ([Account specific calculated fields](https://docs.eazybi.com/eazybi/data-import/data-from-jira/javascript-calculated-custom-fields/account-specific-calculated-fields)).

1. Chose the data type **“Sting”** as results would be tests Yes / No

2. Select the field for data import as **“Dimension”** so you can group and filter data by end results.

3. In the **JavaScript** field, enter the code to compare dates. The logic would be tist to check if issieu has both dates and only then compare them. The code might look like this:

4. I recommend **testing** the code on individual issues, one for each outcome.

On the Cloud and starting eazyBI version 8.0 (which will be released soon), an **AI assistant** can help you write JavaScript code.  
Here are more details on how to work with eazyBI AI assistants: [AI Assistants](https://docs.eazybi.com/eazybi/analyze-and-visualize/ai-assistants)

Best,
