Question

Trying to import CSV file to change the default issue ID. Getting this error.

We found 1 error in your import Missing summary: Summary is a required field in Jira. It can be the task name or an overview of a task. Map the summary field to a CSV column to proceed with the import.

Hi @Satish Ingale ,

Welcome to the community !!

* Summary is a required column in csv during import even though you are just trying to update an existing Jira ticket.
* In the csv file, if there is no Issue KEY mentioned, then jira will create new ticket with the given data. If the Issue KEY is present in csv and you map it during the import, it will update the existing jira tickets with same keys.

Can you describe with an example what are you trying to do with the import? We can suggest you best possible solutions.

Please note: 
"Issue ID" is a unique ID in the backend for jira tickets. It is better not to update them. This will be used in api calls and other backend processes.
