When using the Salesforce Reader and Writer FME leverages an outdated API version to get the metadata it needs to talk with Salesforce. This means that any newer objects, for example most of the FSL Objects, will not be available to map to as tables. This is a very big blocker for us due to FSL being the one place in SF that we use geographic data. We are trying to update our ServiceTerritory object that is in API v38 or later. FME Salesforce Reader Writer is running v37.
