Structure of bill of materials

The Bill of Materials (BOM) is a hierarchical structure, which can be used to provide structural information about your data. For example, the BOM can be used to map the structure of machines and assemblies. The definition of a BOM is optional but recommended because it can be used when searching to easily filter the data.

Basic BOM Structure​

  • The BOM is a tree structure, the nodes in the tree are called assemblies
  • It is not necessary to define a common root node. Multiple root nodes can be defined, which means multiple trees are defined. These root nodes are called "Root Assemblies"
  • Each assembly node can contain multiple sub-nodes. These sub-nodes are called "Sub Assemblies"
  • Assemblies cannot be reused, i.e. each assembly has a maximum of one parent assembly node

Go to section Definition of the Hierarchy to learn about the API for setting up the structure of assemblies.

Assignment of part types to the BOM​

After the BOM structure has been defined, part types can be assigned to assemblies. It is also possible to assign a part type to multiple assemblies (even if they are not at the same level).

Go to section Assignment of part types to learn about the API about assigning part types to assemblies.

Assignment of assemblies to sub-organizations​

A catalog contains one main organization and may contain multiple sub-organizations. The purpose of a sub-organization is to restrict the access to only a portion of the catalog data.

See Data access by groups of users to learn more about organizations in Partium.

The definition of which portion of the data is visible to which organization is done by assigning assemblies to the corresponding sub-organization.

  • Assemblies are always part of the main-organization, which means that all assemblies are always visible in the main-organization
  • An assembly is visible in a sub-organization if it has been explicitly assigned to this sub-organization
  • Only root-assemblies can be assigned to a sub-organization. Sub-assemblies of these root-assemblies are then also visible in the sub-organization
  • Part types are visible in a sub-organization if they are assigned assemblies of that sub-organization.
