Aspect Models

Aspect models are mostly easy to create by transforming a company's internal data into the target aspect model. Transformations are mostly straightforward in these cases. If necessary, special steps in creating aspect models are mentioned in the corresponding sections.

In the following section, all aspect models that are part of Industry Core are documented.

PartAsPlanned

PartAsPlanned represents an item in the Catena-X Bill of Material (BOM) in As-Planned lifecycle status in a specific version.

SingleLevelBomAsPlanned

The single-level Bill of Material represents one sub-level of an assembly and does not include any lower-level subassemblies. In as planned lifecycle state all variants are covered (\"120% BoM\"). If multiple versions of child parts exist that can be assembled into the same parent part, all versions of the child part are included in the BoM. If there are multiple suppliers for the same child part, each supplier has an entry for their child part in the BoM.

PartSiteInformationAsPlanned

The aspect provides site related information for a given as planned item (i.e. a part type or part instance that is uniquely identifiable within Catena-X via its Catena-X ID). A site is a delimited geographical area where a legal entity does business. In the "as planned" lifecycle context all potentially related sites are listed including all sites where e.g. production of this part (type) is planned.

• Version 1.0.0: https://github.com/eclipse-tractusx/sldt-semantic-models/tree/main/io.catenax.part_site_information_as_planned/1.0.0

SerialPart

A serialized part is an instantiation of a (design-) part, where the particular instantiation can be uniquely identified by means of a serial numbers or a similar identifier (e.g. VAN) or a combination of multiple identifiers (e.g. combination of manufacturer, date and number)

Aspect model in GitHub:

Creation of Aspect Model SerialPart

The only special step in creating this aspect model is the initial creation of the Unique ID for the corresponding part.

Batch

A batch is a quantity of (semi-) finished products or (raw) material product that have been produced under the same circumstances (e.g. same production location), as specified groups or amounts, within a certain time frame. Every batch can differ in the number or amount of products. Different batches can have varied specifications, e.g., different colors. A batch is identified via a Batch ID.

Creation of Aspect Model SingleLevelBomAsBuilt

The creation of the aspect model SingleLevelBomAsBuilt is more complicated. This aspect model contains the Unique ID of the manufacturer's part (attribute catenaXId) which is created - as described above - when the part's SerialPart or Batch aspect model is created. But it also contains the Unique IDs of the built-in parts (attributes childItems.catenaXId), as shown in the example above.

For the build-in parts (child items), their Unique ID is not known to the manufacturer initially. Only know are the local ids that are printed on the physical part (serialized part or batch), i.e., manufacturer (BPN), manufacturer part id and serial or batch number. To get the Unique ID of a built-in part, a data provider therefore has to do the following:

• Get all necessary local ids for the built-in part:
  • manufacturer (BPN), manufacturer part id and serial number for serialized parts
  • manufacturer (BPN), manufacturer part id and batch number for batches
