Summary

Line Manager values (parent position incumbent_ are not getting synchronized from Position to the Employee's Assignment Records

Content

Enabled position synchronization at the enterprise level for the below attribute values:

• Manager (Position HCM Hierarchy)
• Department
• Job
• Location
• Full time or Part-time
• Regular or Temporary
• Working Hours and Frequency
• FTE

From the above list of attributes, except the Manager attribute value rest other attribute values like Job, Location, etc…  are getting synchronized with the employee's assignment record as expected with reference to the Position Synchronization Setup at the enterprise level.

I ran the below 2 ESS jobs but still, the Manager field is not getting populated automatically.
