Migrate to the new aBOM API - ION Manual

Actions needed

This project will introduce breaking changes.

1. API: If you are using the API to call any of the below mutations or a query that uses any of the below fields, you will need to update your mutations/queries.
2. Actions: If you have any ION actions (rules) using any of the objects below, those will be disabled when this project is released and you will need to update those after release.
3. Webhooks: If you have any webhooks listening to any of the objects below, you will need to update your webhook listeners after release.
4. Analytics: If you have any SQL queries referencing abom_items or abom_edges those will need to be updated.

If the above does not apply to you then no changes necessary!

Changes overview

Below shows an example of a car assembly that is partially installed and the differences between the old structure and the new structure.

Old structure:

New structure:

Old structure:

• aBOM items represent both the requirement and fulfillment of the installation
• aBOM items are used to link to inventories
• aBOM edges connect aBOM items
• aBOM items change as items are partially installed/removed. New ones get created or deleted, or quantities change

New structure:

• Build requirements belong to parent inventories and represent what needs to be installed
• Build requirements do not change as items are installed into them
• aBOM installations link inventories to a build requirement. The addition of an aBOM installation is an install. The removal of an aBOM installation is an uninstall

Mutation/query changes

• AbomItems will be replaced by BuildRequirements and AbomInstallations, where the requirement and fulfillment (install) are clearly delineated
• AbomEdges will be replaced by PartInventoryBuildRequirements

Below shows the full list of items that are going away.

Going away

Mutations

• InstallKitOnAbomItemChildren
• CreateAbomItem
• DeleteAbomItem
• UpdateAbomItem

GQL Objects/Queries

• AbomItems
• ABomEdges
• ABomItemReferenceDesignators

Fields

• PartInventory.abomItems
• PartInventory.abomChildren
• PartInventory.abomParents
• PartInventory.allChildren
• PartInventory.allParents
• Part.abomItems
• MBomItem.abomItems
• MBomItemReferenceDesignator.abomItems
• AbomItemReferenceDesignator.abomItem

(and any count fields generated from these relationships)

Examples

API: Installing a part

Old structure: Previously, you would have to update an existing abom_item with an inventory to install that inventory. The abom_item at that point may get swapped if the inventory being installed is already linked to an abom_item.

Update aBOM item

mutation UpdateABomItem($input: UpdateABomItemInput!) {
    updateAbomItem(input: $input) {
        abomItem {
            id
            updatedById
            partInventoryId
        }
    }
}

{
    "input": {
        "id": 1,
        "partInventoryId": 1,
        "etag": "etag"
    }
}

New structure: Now installing a part is done via creating an aBOM installation. aBOM installations link inventories to buildRequirements. Conversely, uninstalling a part is done by deleting aBOM installations.

Create aBOM installation

mutation CreateAbomInstallation($input: CreateAbomInstallationInput!) {
    createAbomInstallation(input: $input) {
        abomInstallation {
            buildRequirementId
            buildRequirementReferenceDesignatorId
            partInventoryId
            quantity
        }
    }
}

{
    "input": {
        "buildRequirementId": 1,
        "partInventoryId": 3,
        "quantity": 1
    }
}

SQL: Query for an inventory’s aBOM
