Dear sir,

I want to know how to sync the customer’s components and map them to my Select List (cascading) field “FunctionGroup”.

I search the doc, no such examples, could you please help me? Thanks in advance.

| Map fields | |
| --- | --- |
| Customer JIRA instance | My JIRA Instance |
| Component/s | FunctionGroup Parent field |
| HW | Hardware |
| Cluster | Cluster |
| Infra | Infra |
| BSP | BSP |
| Android-HAL | IVI |
| Audio | Audio |
| MCU | VIP |
| SRS | SYS |
| aaaa | Other |
| bbbb | |
| cccc | |
| dddd | |
| …. | |

Cascading fields are documented in [Syncing cascading select custom fields](https://docs.idalko.com/exalate/x/bwSOAQ)

**Incoming Sync - Target Jira - Untested**

```auto

// get the first component out of the components list sent over from the customer jira
def remoteComponentName = replica.components?.first().name

// component map allows to map the name of the component to the local value
def componentMapping = [
    // "remote component name" : "target parent"
    "HW" : "Hardware",
    "Cluster" : "Cluster",
    "Android-HAL" : "IVI",
]

// Find the mapped value, default to 'Hardware'
def targetValue = componentMapping[remoteComponentName] ?: "Hardware"

def parent = nodeHelper.getOption(issue, "FunctionGroup", targetValue)
issue.customFields."FunctionGroup".value = nodeHelper.getCascadingSelect(parent,"")

```

Let me know if this helps
