An equipment category defines the technical characteristics of an equipment and the views that are available for it. A view profile is a set of views that can be assigned to an equipment category. The views that can be assigned to an equipment category via a view profile are:
Basic data
Classification
Location
Organization
Partner
Status
Structure
Warranty
Manufacturer data
Measurement document
History
Permits
Documents
User fields
Serial data
Configuration
Object links

Explanation
The Preparation and Scheduling phase within phase-based maintenance is the phase where the maintenance planner divides the maintenance effort into manageable groups, levels out the workload over several weeks, determines the concrete time period for the requested maintenance work, and checks the availability of all the resources, spare parts and services needed1.
Option B (The order moves to the Preparation phase once it is approved and released) is correct, because the approval and release of the order is the last step of the previous phase (Approval phase)2. Once the order is approved and released, it is ready for preparation and scheduling.
Option D (The configuration of the order type decides whether you use Resource Scheduling or not) is also correct, because the order type determines whether the order is relevant for resource scheduling or not2. Resource scheduling is an optional step in the Preparation and Scheduling phase, where the planner can assign and dispatch the orders and operations to the technicians using the Resource Scheduling apps2.
Option A (If you use the Resource Scheduling apps, you always dispatch orders and operations) is incorrect, because the Resource Scheduling apps allow the planner to either dispatch or assign the orders and operations2. Dispatching means that the planner assigns a specific technician and a specific time slot for the order or operation, while assigning means that the planner assigns only a technician or a team, but not a specific time slot2.
Option C (Maintenance Planning Buckets give you a list of non-approved notifications) is also incorrect, because the Maintenance Planning Buckets app gives the planner a list of approved and released orders that are ready for preparation and scheduling2. The non-approved notifications are handled in the previous phase (Screening phase)2.

The visible tiles for a specific user in SAP Fiori Launchpad are determined by the PFCG roles that are assigned to the user. The PFCG roles contain the SAP Fiori catalogs and tile groups that define the available and visible tiles for the user.
The steps to set up the visible tiles for a specific user are:
Create or use an existing PFCG role in the backend system that contains the SAP Fiori catalogs and tile groups that are relevant for the user. The catalogs and tile groups can be created or copied from the SAP Fiori Launchpad Designer app. The catalogs contain the tiles and target mappings that represent the apps that can be launched from the launchpad. The tile groups are collections of tiles that are displayed on the launchpad home page.
Assign the PFCG role to the user in the backend system. The user can have multiple PFCG roles assigned, depending on their business needs and authorizations.
Log on to the SAP Fiori Launchpad with the user credentials. The user will see the tiles that are assigned to them through the PFCG roles on the launchpad home page. The user can also personalize the launchpad by adding, removing, or rearranging the tiles and groups.
The other options are incorrect because:
Portal roles are not used to assign SAP Fiori catalogs and tile groups. Portal roles are used to assign portal content, such as iViews and pages, to users in the SAP Enterprise Portal.
Assigning the tiles directly to the user is not possible. The tiles are part of the catalogs and tile groups that are assigned to the user through the PFCG roles.
