Even though you cannot enter nonalphanumeric characters for the source system code, you can for the source system name and description. Use the name and description to provide information that is more descriptive than the code. Alternatively, you can enter the same value for the source system code and name.
Source system codes are used in the mapping records, for references between source IDs and Registry ID, for example to query mapping records. Users should enter the source system code when they load data into the TCA Registry.
Attention: You cannot update the source system code or type after you first define them.
You can also create a source system in the context of any of the following:
Party
Party Site (Address)
Organization Contact Purpose
Contact Points - Phone Numbers, Email, and URL
Account
Accounts
Account Contacts and Account Site Contact
Account Site
Account Site Purpose
You can specify the status of the source system only when you update, not create, it.
See: Single Source of Truth Overview.
The source system can provide data for all displayed entities. Optionally select the type of additional details to enter for the entities. Aside from the seeded Source System Table Name, other additional details are available if flexfields are set up. See: Flexfields for Defining Entities.
Note: For any entity, you cannot allow multiple references from the D&B source system to one TCA record.
