My bulk import is not creating, just updating

[Josh Thaler]

I am working on a CSV template to create an Epic and child tasks. The intention is to use this template to create multiple Epics with the same child tasks.

Import1 works as expected, creating IM-1 through IM-11. Import2 also works, creating IM-12 through IM-21.

The problem is on the 3rd import.

On the 3rd import, it does NOT create anything new, instead updating all the tickets in Import1, IM-1 through IM-11.

This has happened in both Test projects I have created.

I am following all the relevant documentation Parent Child Mapping Import Using CSV Creating issues using CSV 

Here is the template CSV.

For each subsequent import, the info in <> is replaced with unique text. The Work item Key, Work item id, and Parent values are incremented for each import to prevent conflict. 

Work type,Work item Key,Work item id,Parent,Status,Summary,Description

Here is the relevant section from the Import log when it updates instead of creating

Hi @Josh Thaler ☺️ when "the intention is to use this template to create multiple Epics with the same child tasks" why not use a template? you can reuse multiple times in different projects? 

If you're open to using a third-party app for your cloud instance, I think Templating.app could be a good alternative

• You can easily create issue templates for hierarchies epic, issue, subtask.

This is how this can look like:

Hello, Good day. It looks like the work item key : CIN-1-4 was already present on your site. While importing the .CSV file map only summary, description and other fields. Do no map work item key and work item ID and check the status. Thanks
