# Writing to SAP OData


 This section describes how to write data to your SAP OData Service using the Amazon Glue connector for SAP OData. 

**Prerequisites**
+ Access to an SAP OData service
+ An SAP OData EntitySet Object you would like to write to. You will need the Object name.
+ Valid SAP OData credentials and a valid connection
+ Appropriate permissions as described in [IAM policies](https://docs.aws.amazon.com/glue/latest/dg/sap-odata-configuring-iam-permissions.html)

The SAP OData connector supports two write operations:
+ INSERT
+ UPDATE

While using the UPDATE write operation, ID\$1FIELD\$1NAMES must be provided to specify the external ID field for the records.

**Example:**

```
sapodata_write = glueContext.write_dynamic_frame.from_options(
    frame=frameToWrite,
    connection_type="sapodata",
    connection_options={
        "connectionName": "connectionName",
        "ENTITY_NAME": "entityName",
        "WRITE_OPERATION": "INSERT"
    }
```
