# SAP Integrations in Python

Connect to SAP S/4HANA, ECC and SuccessFactors from Python, reading and writing business data.

## Get started

Connect to S/4HANA and ECC through Gateway services - service roots, OData V2 and V4 paths, CSRF tokens and the sap-client parameter.

[SAP S/4HANA and ECC](https://zato.io/docs/dev/sap/s4hana/index.html)

service.py

```
# Read business partners from S/4HANA
conn = self.sap['SAP.Sample']
partners = conn.read('A_BusinessPartner',
    filter="CityName eq 'London'", top=20)

partners[0]['BusinessPartnerName']
'Acme Ltd'

len(partners)
20
```
