Trading Community Architecture: TCA Guide in Oracle EBS

Introduction: Why Trading Community Architecture Matters

Oracle Trading Community Architecture(TCA) is a complex data model for managing third parties in Oracle EBS system. TCA manages the complex information of customers, suppliers, banks, employees and contact data in Oracle Apps R12. TCA centralizes and standardizes records across modules, reducing errors and duplication. With Trading Community Architecture, each entity—like customers, employees, banks or suppliers—is modeled as a “Party” with structured addresses, contact points, and accounts.

Imagine your warehouse ships a product to the wrong address because the customer had three profiles with conflicting addresses. Finance sends an invoice to another wrong address. Now the customer is angry, and your team is stuck resolving the mess. This is where TCA saves the day

This unified data model improves billing accuracy, shipping reliability, and reporting quality. TCA also supports data quality tools and API integration, making it essential for clean, efficient enterprise data. For organizations using Oracle EBS R12, a well-structured TCA is key to better decisions and stronger business relationships.

TCA is a structure inside Oracle E-Business Suite R12 that manages party and account information in one place. TCA acts like a master list for all the people and organizations your business deals with. With it, you can clean, manage, and use your data better across departments.

Let’s begin our journey by dissecting the foundational data model that powers TCA.

Understanding the Trading Community Architecture Data Model

What is a “Party”?

A Party is an entity in the TCA Registry that can enter into business relationships. This could be:

• A Person (e.g., Priya Desai)
• An Organization (e.g., GreenView Hotels)
• A Relationship (e.g., Priya Desai as a contact for GreenView Hotels)

Each party is assigned a unique Registry ID. TCA stores rich information for parties, including names, addresses, contacts, and communication methods. For example, Priya Desai might have a personal phone number, and a different number when acting as GreenView Hotels’s contact.

Party Relationships

These define how two parties are connected. Types include:

• Person-to-Organization (e.g., Priya as an employee of GreenView Hotels)
• Org-to-Org (e.g., Division to Headquarters)
• Person-to-Person (e.g., Legal guardianship)

Relationships are dynamic, reciprocal, and unlimited. They help you model roles, responsibilities, and business linkages within the trading community.

The Trading Community Architecture Object Hierarchy

1. Party – The core entity (e.g., “GreenView Hotels”)
2. Party Site – A location tied to that Party for a specific use (e.g., mailing address)
3. Contact Point – Means of contact like phone or email
4. Account – A business relationship such as a customer or supplier account
5. Account Site – A party site used in the context of an account (e.g., billing or shipping address)
6. Site Use – Describes how an address is used (e.g., Bill-to, Ship-to)
7. Location – A geospatial point defined by an address
8. Contact – A person connected to a party through employment or business relationship

Party vs Account

• A Party exists even if no business is done.
• An Account exists only when there’s a business relationship.

CRM uses the Party layer. ERP uses the Account layer. Together, they form a complete Customer.

TCA Components and Functional Areas

1. Party Management

TCA allows businesses to create, update, and manage a wide array of party data:

• Maintain parent-subsidiary relationships
• Create individuals, organizations, or relationships
• Manage party classifications (e.g., customer vs. vendor)

Data Quality Management:

• Duplicate prevention via Oracle DQM
• Standardization of naming conventions
• Matching rules for new party creation

2. Account Management

An “Account” in TCA signifies the formal transactional relationship you have with a Party. Importantly, a single Party can have multiple Accounts representing different facets of your engagement.

Key Functions:

• Creation and management of both customer and supplier accounts, tailored to the specific relationship.
• Establishment of hierarchical account structures, crucial for managing global accounts with numerous operating entities. Example: A global retailer with separate accounts for each regional division.
• Configuration of financial parameters at the account level, including credit limits, payment terms, and preferred billing cycles.

3. Site & Site Use Management

Party Site: This is a relationship between a location and a party that indicates that a location exists for that party. It stores address information.

Account Site: Links address to specific accounts.

Site Use: Defines how that location is used in transactions.

Primary uses include:

• Bill-to
• Ship-to
• Sold-to

Site data accuracy ensures smooth transaction processing, correct tax jurisdiction, and proper delivery of goods/services.

4. Contact Management

TCA facilitates the management of key contacts at both the overarching Party level and the more specific Account level. Contacts can be associated at both party and account levels. Link contacts to multiple accounts and sites.

Key Capabilities:

• Assign contacts to parties or accounts
• Define contact details and roles
• Share contacts across entities.

5. Trading Community Data Hub (TCDH) [Advanced/Optional]

For organizations grappling with master data residing in disparate systems, TCDH extends the power of TCA. It acts as a central, authoritative repository for consolidating and governing trading partner master data.

TCDH is especially useful for multinational organizations dealing with multi-source data integration.

Key Advantages:

• Single version of customer and supplier truth
• Advanced duplicate detection algorithms
• Seamless integration with legacy systems

Key (Trading Community Architecture) HZ Tables in Oracle Apps R12

TCA data model uses many tables to store the TCA information in structure way. You can understand the overview of the TCA(HZ) Tables in Oracle Receivables.

How TCA Works: The CamPrint India Story

CamPrint India Pvt. Ltd. is a tech retail company based in Bengaluru. They sell cameras and printers in-store and online. They serve both individual buyers and corporate clients like hotels and educational institutes.

Party

One day, a person named Ravi Sharma visited CamPrint’s Mumbai store. He inquired about a Canon EOS camera but didn’t buy. Still, he shared his name and mobile number. CamPrint saved his information.
In Oracle TCA, Ravi became a Party — a person or organization known to the business. He wasn’t yet a customer because no transaction had taken place.

At the same time, GreenView Hotels Pvt. Ltd., a hotel chain from Ahmedabad, contacted CamPrint. They needed electronics for their new hotel in Goa. CamPrint created another Party for GreenView Hotels. Now, two parties existed:

• One for Ravi (person)
• another for GreenView (organization)

Contact

GreenView’s Priya Desai, called on behalf of her company. She introduced herself and shared her email and phone number.

CamPrint created a Contact for her — a person representing the organization.

Contact Point

Priya’s phone number and email address were saved too. These were stored as Contact Points. They are ways to reach the contact — phone, email, fax, etc. Each contact can have multiple contact points.

Relationship

CamPrint also needed to know how Priya was related to GreenView Hotels. She was authorized to negotiate on behalf of her company.

This relationship — Priya is a purchasing officer at GreenView — was saved as a Relationship. This is stored in the HZ_RELATIONSHIPS table.

Relationships can be:

• Person to Organization (Priya to GreenView)
• Organization to Organization (Parent company to branch)
• Person to Person (e.g., family link)

Customer Account

After initial discussions, GreenView placed their first order. They were no longer just a party — they became a Customer.

CamPrint created a Customer Account for them. Now, GreenView had commercial terms, payment history, and credit information attached.

Party Site

GreenView wanted the printers delivered to their new hotel in Goa. They also wanted invoices sent to their finance team in Pune. CamPrint first created Locations — Goa and Pune addresses.

Then they created Party Sites — links between GreenView and those physical locations.
This tells the system: GreenView is associated with these places.

Customer Account Site

The party sites became Customer Account Sites. These are the shipping and billing points tied to a Customer Account.

So, CamPrint added:

• Goa as a SHIP-TO site
• Pune as a BILL-TO site

Both of these belong to GreenView’s customer account.

Account Site Usage

Each Customer Account Site was tagged with a Usage:

• Goa: SHIP_TO (delivery address)
• Pune: BILL_TO (invoice address)

This is stored as Account Site Usage. It defines the purpose of each address in business transactions.

Back to Ravi – From Party to Customer

A month later, Ravi Sharma came back to buy the Canon EOS R8. Now, CamPrint converted him from a Party to a Customer. They created a Customer Account for him.

His home address in Andheri became a Customer Account Site. He chose to ship it there, and the same address was used for billing.

CamPrint added his email and mobile as Contact Points again. Now linked to both his party and customer account.

TCA in Action

Later, GreenView expanded. They opened new hotels in Jaipur and Ooty.
Each hotel got its own Customer Account. But they were all linked to the main corporate party (GreenView Hotels Ahmedabad).

This parent-child link was stored in HZ_RELATIONSHIPS.

Thanks to Oracle TCA:

• There were no duplicate customer records
• Every address and role was reused where needed
• Support teams always knew whom to call
• Sales teams had a 360-degree view of each client
