Not found for export command 4280201

Hi,

I recently started getting an error on some of my schedules:

Scheduled job failed: Source object id="{B00BE606-22A6-4254-9C45-E6A9329FA52F}" not found for export command 4280201

These schedules are setup as batch for multiple dimension members.

Can anyone tell me what does it mean and which impact it has on the reports? 

Thank you in advance
