# ol set property

Add additional properties to an Asset or Asset's Field

The **ol set property** command lets you manually assign a property to an asset metadata model. In the usual case, the parser automatically generates all the asset model properties by parsing the data source. However, if a required property is not included in the data source, you can add it to the asset metadata model with the help of this command. 

The command inserts the added properties wrapped in the **additionalAttributes** object at one of two possible locations within the asset metadata model hierarchy: at the asset level or the input or output entity definitions under a specified field.

At the asset or entity level: 

```
{
    "id": "f54e33df-6ec4-4e5f-96d4-ad9f9fa71636",
    "name": "oactcs9",
    "path": "OACTCS9",
    "additionalAttributes": {
        "param-1": "value1",
        "param-2": "value2",    
    },
    "inputEntityDefinition": {
        ...
    },
    "inputEntityDefinition": {
        ...
    }, 
}
```

At the input or output entities under a specified field:

```
{
    "id": "f54e33df-6ec4-4e5f-96d4-ad9f9fa71636",
    "name": "oactcs9",
    "path": "OACTCS9",

                        "fields": {
                            "actiAccountId": {

                                "legacyType": "org.openlegacy.core.model.legacy.type.MainFrameLegacyTypes.Char",
                                "additionalAttributes": {
                                    "param-1": "value1",
                                    "param-2": "value2",    
                                }

                            },
                            "actiCustomerId": {
                                ...
                            },
```

## Syntax

ol set property \[OPTIONS]

## Options

**--property**

The key and value of the assigned property

```
--property test foo
```

**--asset** (required)

The name of the asset to which the property is assigned.

```
--asset oactcs9
```

**--field**

The full-path asset field under which the property is added. If omitted, the properties will be added to the asset level.

```
--field oactcs9.dfhcommarea.input.actiAccountId
```

**--direction**

For asset only, sets the direction for property lookup: INPUT, OUTPUT or BOTH (default: BOTH).

```
--direction input
```

**--outputStatusCode**

The status code under which to add a property under the **outputEntityDefinitionMap** of the asset metadata model. For Operation asset only, sets output status code for OUTPUT/BOTH direction. The default status code is 200, but the property is helpful when the asset can have multiple status codes.

```
--outputStatusCode 406
```

Adding a property under the default **200** status code:
