In today’s digital business landscape, seamless data integration is essential—and that’s exactly where OData services come into play. Whether you’re a tech enthusiast taking your first steps or a company employee aiming to upskill, understanding how to create a Deep Insert in an OData service can give you a serious edge in the data-driven economy.
Let’s break this down into simple, actionable steps and understand the value of mastering this concept.
🚀 What is OData and Why Should You Care?
OData (Open Data Protocol) is a web protocol developed by Microsoft that allows the creation and consumption of queryable and interoperable RESTful APIs. Think of it like a smart bridge that lets different systems talk to each other with ease.
Now, here’s the exciting part: Deep Insert.
A Deep Insert is a powerful function that lets you create multiple related records in a single OData call. Instead of saving one table entry at a time (which can be painfully slow), you can create a main entity and all of its related entities in one go.
It’s like ordering a full meal instead of picking each dish one by one.
💡 Real-World Use Case: Why Deep Insert Matters
Imagine you’re creating a Sales Order in an ERP system like SAP. You want to input the order header (customer details, order date) and all order items (products, quantities, prices) at once. A Deep Insert allows you to push both the header and the items into the backend system in a single operation—saving time, reducing errors, and improving system performance.
🧠 Industry Insights: Market Trends & Skills in Demand
With the rise of SAP S/4HANA, API-first strategies, and cloud-based solutions, companies are rapidly shifting to modern interfaces like OData. Developers who understand how to work with Deep Insert are in high demand across industries like:
- Manufacturing (for managing production orders)
- Retail (for managing customer transactions)
- Logistics (for shipping and delivery data)
- Finance (for bulk posting financial documents)
Understanding this process not only boosts your technical know-how but also opens doors to career advancement.
🛠️ Step-by-Step: How to Create a Deep Insert in OData Service
Let’s walk through the steps in an easy, beginner-friendly way.
1. Understand Your Data Model
Before you start coding, know your structure. You typically have:
- A header entity (e.g., SalesOrder)
- A line item or child entity (e.g., SalesOrderItems)
These are connected via an association and navigation property.
2. Define Associations and Navigation in SEGW
In the SAP Gateway Service Builder (transaction code SEGW):
- Create your header and item entities.
- Define the association between them (1:N relationship).
- Create a navigation property linking them.
This setup tells the system that one sales order can have many items.
3. Implement CREATE_DEEP_ENTITY Method
In your Data Provider Class (DPC_EXT), redefine and implement the method CREATE_DEEP_ENTITY.

CopyEdit
METHOD salesorder_create_deep_entity.
DATA: ls_header TYPE zsalesorder,
lt_items TYPE TABLE OF zsalesorderitem.
” Extract header data
ls_header = is_data.
” Extract item data from the navigation property
lt_items = is_data-salesorderitems.
” Custom logic to insert header and items in DB
CALL FUNCTION ‘Z_CREATE_SALES_ORDER’
EXPORTING
i_header = ls_header
i_items = lt_items.
” Return the created entity
er_entity = is_data.
ENDMETHOD.
4. Test the Deep Insert Using Gateway Client
Use transaction /IWFND/GW_CLIENT to test your service. POST a payload like:
json
CopyEdit
{
“SalesOrderID”: “SO123”,
“CustomerName”: “John Doe”,
“SalesOrderItems”: [
{
“ProductID”: “P001”,
“Quantity”: 2
},
{
“ProductID”: “P002”,
“Quantity”: 1
}
]
}
If everything is set up correctly, your OData service will create the sales order with all its items in one seamless call.
🔍 Pro Tips for Beginners
- Start Small: Test with just one item before adding multiple entities.
- Use Debugging: Set breakpoints in CREATE_DEEP_ENTITY to inspect data flow.
- Stay Clean: Keep your associations and navigation properties consistent and clear.
- Use Annotations: Add proper metadata to improve UI integration (especially in Fiori apps).
