A main design part is related to an object to provide the object with a physical piece of equipment. Additional parts are secondary design parts used to:
A design part will often consist of multiple additional parts.
Additional parts purchase quantity is the number of items required for purchase. Documenting additional parts may also show the composition of the object. For example, a centrifugal pump could have additional parts for casing, bearings, impellers, nuts and bolts, and axels. By creating each of these parts as additional parts, the design object is completely documented, and equipment in the correct amounts may be purchased.
Spare parts for the object are created for the express purpose of creating a spare parts list in IFS/Equipment. For example, an impeller is registered as a design part and then assigned as an additional part to a centrifugal pump object. After the pump's design status is changed to Planned for Operation or Completed, the pump is created as an equipment object in IFS/Equipment. Each of the attached additional parts is copied to the equipment object in IFS/Equipment as a spare part.
Often a discussion between the design engineer and the maintenance department takes place to determine which additional parts will be sent over with the object to become spare parts. From IFS/Equipment, spare parts may be added/removed as required.
Note: An additional part must have a part number for it to be copied to the equipment object in IFS/Equipment. This is because the spare part is stored as an inventory part for the transferred object.
IFS Business Analytics can be used to create and analyze information based on the additional parts list (Bill of Materials) data available in IFS Applications. For more information refer to About Information Sources in IFS Business Analytics.
An Additional Parts folder is set up for a design object class using the Can Have An Additional Part class relation. Within a Tree View, this relation creates an Additional Parts folder below the object. An Additional Parts For folder can be set up for a design part class using the Can Be An Additional Part For class relation.
An additional part can be created from an existing design part on the Design Part Consists of or Additional Parts windows. The Additional Parts window is opened by highlighting the object's Additional Parts folder. The Design Part Consists of window is opened by expanding the design part's folder and selecting the Consists of right mouse button option. An additional part is defined within the Additional Parts window by creating a new row and inserting a registered design part in the Design Part ID field. Within the Additional Parts window, there are three fields to store information about the equipment drawings and where these additional parts are located. These fields are:
Within both of the additional part windows, there are two fields for registering additional parts.
An optional sort order determines the relational display order of each additional part; the lowest sort number displays first under its folder in a tree view.
The first time a design part is connected to an object, the design part is also created automatically as an additional part to that object. Both the purchase quantity and the additional part quantity are set to 1. If the same design part connected to the object is exchanged with another design part, the additional part connected to the object is also exchanged automatically.
An object's additional parts can also be updated manually. Changes to the design part's additional parts can be copied over to the object by selecting the Inherit Additional Parts from Design Part option on an object. Alternatively, additional parts may be added directly to the object without using the design part as a template.
The design part with the predefined additional parts serves as a template for the automatic creation of additional parts for an equipment object. These additional parts are automatically inherited by the equipment object when the design part is connected to it.
Additional parts will not be inherited if the equipment object's class does not have the additional parts class as an allowable class relation. Additional parts will not be inherited if the equipment objects have those additional parts added manually.
A design part of the PUMP class consists of two design parts: one of the BEARING class and one of the FAN class. An object of the PUMP class is created and according to the class setup, this object class can have additional parts of the BEARING class only (not FAN). When the design part is connected to the object, the additional part of the BEARING class will automatically be inherited as an additional part to the object, but the other design part of the FAN class will be ignored.
This behavior makes it possible to define two different types of design parts using the Consists Of relation. You can define design parts that serve as spare parts to enable the spare part inheritance for objects (compare with the design part of the BEARING class above). You can also define informational design parts to show what the design part actually consists of (compare with the design part of the FAN class above). The latter type of design parts is not inherited as a design part to objects if the class is not set up to support this.
The possibility exists that the design part has both the ability to serve as a additional part for objects and as information as to what a design part consists of (class relation settings must be set up to support this).
Additional parts are attached to the object when the object status is Under Design, Planned for Operation, or ReDesign. When the object's design is complete, the object's design status is changed to Completed, which creates an equipment object in IFS/Equipment. The additional parts are transferred to the equipment object along with the rest of the object information.
Additional parts should not be added to the object within IFS/Asset Design after the design status has been changed to Completed because those additional parts will not be transferred to the equipment object in IFS/Equipment. Spare parts can, however, be added to the equipment object in IFS/Equipment.
An additional part connected to an object is a shortcut to the design part. Deleting the additional part under the object removes the shortcut to the design part, but does not remove the design part.
