In employee details reports to field is automatically changing

i changed reports to team lead id from project manager after two days it automatically change back to project manager id

please check if there is a Workflow or Notification applied which causes this to happen. A further thing might be a “fetch from” setting in that field.

Further you might have custom scripts applied which can trigger such a change.

if i’m assigning the any employees to a TL some them only not showing for the TL, not all.
I don’t know why it’s happening.
