• Simple API - One client, one method signature for all operations
• Automatic URL Building - Handles complex SAP URL patterns automatically
• Input Validation - Clear error messages for missing parameters
• Raw Responses - Returns actual API response with helper methods to extract data

Installation

pip install sap-odata-python

Quick Start

from sap_odata import ODataClient

# Connect to SAP system (sap_mode=True is default)
client = ODataClient(
    "https://sap-system.company.com:44300",
    username="your_user",
    password="your_password",
    client="100"
)

# SAP OData V4 (RAP Services)
response = client.get(
    service="zsd_my_service",
    entity="MyEntity",
    version="v4",
    namespace="zsb_my_service",
    top=10
)

# SAP OData V2 (Gateway Services)
response = client.get(
    service="ZMY_SALESORDER_SRV",
    entity="SalesOrderSet",
    version="v2",
    top=10
)

# Extract data using helper methods
items = client.get_value(response, "v4")
for item in items:
    print(item)

SAP URL Patterns (Handled Automatically)

Version	URL Pattern
V4	/sap/opu/odata4/sap/{namespace}/srvd_a2x/sap/{service}/0001/{entity}
V2	/sap/opu/odata/sap/{service}/{entity}

You just provide service, entity, and namespace (for V4) - the library builds the full URL.

API Reference

Constructor

client = ODataClient(
    host,              # SAP system URL
    username="",       # SAP username
    password="",       # SAP password
    client="",         # SAP client number (e.g., "100")
    sap_mode=True,     # True for SAP, False for other OData services
    verify_ssl=True,   # SSL verification
    timeout=60         # Request timeout
)

Methods

Method	Description
get(service, entity, version, namespace, **params)	Read data (GET)
post(service, entity, data, version, namespace)	Create record (POST)
patch(service, entity, data, version, namespace)	Update record (PATCH)
delete(service, entity, version, namespace)	Delete record (DELETE)
metadata(service, version, namespace)	Get service metadata (XML)
get_value(response, version)	Extract entity array from response
get_next_link(response, version)	Extract pagination URL

Query Parameters

Parameter	Example	Description
top	top=10	Limit results
skip	skip=20	Skip records
filter	filter="Price gt 100"	Filter expression
select	select="ID,Name"	Select fields
expand	expand="Items"	Expand navigation
orderby	orderby="Name asc"	Sort results

Response Format

Responses are returned raw (as received from the API):

# V4 response
{"@odata.context": "...", "value": [...], "@odata.nextLink": "..."}

# V2 response
{"d": [...]}  # or {"d": {"results": [...], "__next": "..."}}

Helper Methods

# Extract entities from response
items = client.get_value(response, "v4")
items = client.get_value(response, "v2")

# Get pagination URL
next_url = client.get_next_link(response, "v4")
next_url = client.get_next_link(response, "v2")

Non-SAP OData Services

For public services like Northwind, set sap_mode=False:

client = ODataClient("https://services.odata.org", sap_mode=False)

# Northwind V4
data = client.get("V4/Northwind/Northwind.svc", "Products", top=5)

# Northwind V2
data = client.get("V2/Northwind/Northwind.svc", "Products", version="v2", top=5)

Error Handling

from sap_odata import ODataClient, ODataError, ODataConnectionError, ODataAuthError

try:
    data = client.get("zsd_my_service", "MyEntity", version="v4", namespace="zsb_my_service")
except ODataAuthError:
    print("Authentication failed")
except ODataConnectionError as e:
    print(f"Connection failed: {e}")
except ODataError as e:
    print(f"OData error: {e}")

Context Manager

with ODataClient("https://sap.company.com", "user", "pass", client="100") as client:
    data = client.get("ZMY_SRV", "OrderSet", version="v2")
