The HZ_ORIG_SYS_MAPPING table stores information about source systems and the TCA entities that the systems can provide data for. The HZ_ORIG_SYSTEM_REFERENCES table stores information about the references between source IDs and TCA Registry IDs.

For both tables, you can set up flexfields to store additional information. Flexfields are additional data fields that can be customized for your organization's business needs. You must compile the flexfield Source System Entity Mapping (HZ_ORIG_SYS_MAPPING) for the Receivables (AR) application before using it. See: Overview of Setting Up Flexfields.

Flexfields for Defining Entities

If flexfields in the HZ_ORIG_SYS_MAPPING table are set up, you can enter flexfield values when you define entity settings as part of creating or updating source systems.

For example, you set up a First Import Date flexfield to store the date when the source system is first used to import data. You then create a source system, select First Import Date for additional details, and enter a date for specific entities. See: Creating and Updating Source Systems.
