# Auto Set Custom Attribute ## Scenario Every time a part is created, set the custom attribute `Tracking Strategy` based on the following table: | Tracking Level | Sourcing Strategy | Tracking Strategy | | -------------- | ----------------- | ----------------- | | None | Make | N/A | | None | Buy | N/A | | Lot | Make | Lot - Make | | Lot | Buy | Lot - Buy | | Serial | Make | Serial - Make | | Serial | Buy | Serial - Buy | ### Trigger The flow should be triggered when a part is created. ### Steps * Create a new flow using the [ion-webhooks](https://manual.firstresonance.io/workflow-builder/ion-webhooks-component) component. Configure the ion-webhooks step by setting the Connection, providing a name for the webhook receiver, and adding an action. In this example we want the flow to be triggered when a part is created so the action will be `Parts - Create`

* Add a step that uses the `First Resonance ION` component. Click on the `+` icon at the bottom of the flow then search for `First Resonance ION`. Click on `Run GraphQL Query`.

Configure the Connection, GraphQL Query, and GraphQL Variables

Use the following query: ```graphql query getParts($filters:PartsInputFilters!) { parts(filters:$filters) { edges { node { id _etag partNumber sourcingStrategy trackingType } } } } ``` Use the following query variables: ```json { "filters": { "id": { "eq": } } } ``` Add a reference in the query variable to the incoming id from the webhook trigger

Refer to [this](https://manual.firstresonance.io/workflow-builder/first-resonance-ion-component/using-the-first-resonance-ion-component) for detailed documentation on using the First Resonance ION component. * Add a step that branches based on the value of the Tracking Level. Search for "branch" and select `If Condition is Met`

Configure the branch step to check the Tracking Level:

Click the icon in the first `Field` and configure the input to the output of the previous step.

Select `does not exist` for the Operator

* Click on the `+` icon in the "Tracking is None" side of the branch. Search for "Execution save value". Select `Execution - Save Value`

Enter `trackingStrategy` for the Key and `N/A` for the Value

* Click on the `+` icon in the "Else" side of the branch. Search for "Execution save value". Select `Execution - Save Value`

Enter `trackingStrategy` for the Key Enter references to the `trackingType` and `sourcingStrategy` for the Value separated by a -

* Add a step at the end of the flow that will return the value of `trackingStrategy`. Click on the `+` icon at the bottom of the flow then search for "Execution get value". Click on `Execution - Get Value`

Enter in `trackingStrategy` for the Key

* Add a step to set a custom attribute to the value of `trackingStrategy`. Click on the `+` icon at the bottom of the flow then search for "First Resonance ION". Click on `Run GraphQL Query`.

Configure the Connection, GraphQL Query, and GraphQL Variables

Use the following query: ```graphql mutation UpdatePartAttributes($input: UpdatePartAttributeInput!) { updatePartAttribute(input: $input) { partAttribute { partId Etag key value } } } ``` Use the following query variables: ```json { "input": { "partId": , "key": "", "value": "", "etag": "" } } ``` Add a references in the query variable to the partId, etag, and value. Reference to the partId:

Reference to the etag:

Reference to the value:

The query variables should look like this:
