Trading Community Architecture (TCA) is the new name for all trading partners, suppliers, customers, banks, and employees.
This new framework stores and tracks the data of all these entities.
TCA is a new product released in a prior release of E-Business Suite. In R12 this has been formalized and now owns all the partners that the enterprise deals with. This leads to a difference in the technical and functional aspects of how these data sets are managed in R12.
The most important reason to bring up the TCA is to explain briefly how address validation is managed. The following screenshot shows a depiction of how address validation for U.S. addresses can be configured:
You can manage the structure and the validations using these screens individually.
