The job title is read directly from Job Information instead of Employee Profile for Global Assignment and Concurrent Employment. For a single employment it is derived from Employee Profile directly instead.
Reproducing the Issue
1. Configure Job Title field as a picklist field:
2. Check an employee without global assignment, observe the Job Title value from the header:
3. Check an employee with a global assignment record, observe the Job Title value from the header:
4. Print PDF preview:
5. Export master picklist file from your instance and verify the IDs showing up from the header:
If the job title field is configured as a picklist field in job information, the option ID is read instead of the label of that picklist for the header information of Globally Assigned employees. The job title field is not always configured as a plain string and if the Job title field would be configured as a picklist, this problem would arise.
This defect is fixed in the b1811 release.
