Hi all, I've ran into a problem showing the relationship between issues. "Blocks" relationship. * My Import is a CSV from external import. * This means the relevant fields that I have that's unique: Issue ID, Issue Type, Outward issue link (Blocks). * attached the sample screenshot of the error message that i receive.

Hello Team, While linking issues in Jira (such as parent tasks, sub-tasks, or other issues) using relationships like “Relates” and “Blocks”, please ensure the correct CSV format is used. Below are the steps to import issue links through a CSV file. In this example, we are linking ABC-1, ABC-2, and ABC-3 using the link types “Relates” and “Blocks”: Prepare the CSV file in the required format (as shown in the reference example).

Select your project. In the field mapping screen, use the search bar and type “Link ”. Select the appropriate issue link types (for example, Link “Relates”, Link “Blocks”, etc.).

Please make sure all fields are reviewed carefully before importing to avoid any linkage issues. Thank you.

Hello @Shanavash Mohamedismail

Welcome to the Atlassian community.

Please provide an example of the data you are importing, and the column-to-field mapping you specify for the during the import configuration.

Are you trying to create subtask through this CAV import?

If so, do the parent issues already exist in Jira or are you trying to create those during the import also?
