Please resolve above issue ASAP. Thank you

Service Unit / Practitioner Schedules are overlapping

How to fix that error. Thank you in advance.

i tried a few scenarios and figured that if the service unit set in practitioner schedule does not exist this can happen. Ideally it’s a link field and should not have allowed to delete, not sure how this could have happened. Could you please verify the service unit selected in the practitioner schedule table in practitioner master has a valid service unit?

How many practitioners Schedule do you have ?

Thank you. issue is solved
