# Use case
Several teams use the [ePub workflow](https://appfire.atlassian.net/wiki/download/attachments/68749863/ePub-workflow-diagram.png?version=1&modificationDate=1521470932712&cacheVersion=1&api=v2) to coordinate an eBook creation process. **When an eBook transitions from Open to Draft, a new sub-task needs to be created in the backlog of an “IT Services (IS)” project** so the IT team’s manager can begin to forecast and assign resources.
Check out the below step-by-step instructions on how to automate sub-task creation based on the above scenario.
# Steps

| --- | --- | --- |
|  | ## Isolate the Workflow Transitions (ID) for new Create Sub-task Post Function
Logged into Jira as a workflow administrator:
1. Navigate to ***Project Settings → Workflows.***
2. Click the respective **Edit **link of the required Scheme, in the Actions column.
3. Click the link name of the Transitions (ID) for which you want to add a *Create Sub-task* post function. |  |
|  | ## Add Post Function
1. Select the *Post Functions* tab.
2. Click the *Add post function* link.
3. Select the *Create Sub-task *post function.
4. Click the **Add** button listed below the options. |  |
|  | ## Define Issue Fields
1. Select the *Basic Fields* tab:
1. Retain the default *Summary *as "%parent_summary%", so we inherit the same summary as the parent issue.
2. Enter "FYI - ePub sub-task workflow initiated" in the *Description *field.
2. Select the *Detailed Fields* tab:
Within the details: Select "Sub-task" as *Issue type*
1. Under People:
1. Select "Current user" as *Reporter.*
2. Select "Parent issue's assignee" as *Assignee.*
3. Select the *Links* tab:

|  | ## Publish and Validate Post Function
1. Click the **Publish Draft** button to publish changes to your workflow and activate the Create Sub-task post function. Backing up your workflow ahead of publishing is always a good idea. However, in this case, simply publish without a backup.
2. Navigate to your project in Jira. In this case, navigate to the ePub project.
3. Create a new issue and then transition to the step where your new Create Sub-task post function is configured. In this case, this is the *In Draft* step.
4. Search for new sub-tasks within your project. You should see the new sub-task automatically created with the values you defined in the previous step. |  |
