I'm receiving a variety of deployment errors related to OpportunityLineItemSchedule. For example:
sObject type 'OpportunityLineItemSchedule' is not supported. If you are attempting to use a custom object, be sure to append the '__c' after the entity name. Please reference your WSDL or the describe call for the appropriate names.
Didn't understand relationship 'OpportunityLineItemSchedules' in FROM part of query call. If you are attempting to use a custom relationship, be sure to append the '__r' after the custom relationship name. Please reference your WSDL or the describe call for the appropriate names.
Entity is not org-accessible entity name: OpportunityLineItemSchedule
How can I resolve these errors?
