MDM SaaS uses unique identifiers to identify master records, source records, and field groups.
Business ID
Business IDs are unique identifiers of master records that belong to a business entity. You can configure a business ID format for a business entity when you configure the business entity properties. For more information about configuring a business ID format, see Business ID format.
When you create records from the user interface, MDM SaaS assigns a business ID based on the configured business ID format. You can specify business IDs for records that you ingress through ingress jobs. For more information about ingressing data with business ID, see Ingress data with business ID.
When you create records through the Create Master Record API, you can specify business IDs for the records. For more information about using the create master record API, see Create master record.
Note: Business users can't specify business IDs for records that they import into business applications.
Field group ID
Field group IDs are identifiers of the field group entries. For example, when you have five address entries, each address is identified by a unique field group ID. However, these field group IDs can be used by entires in another field group, such as phone numbers.
You can specify field group IDs for the records that you ingress through ingress jobs or through the create master record API. You can specify the field group ID through the _id parameter when you create a business entity master record through the create master record API. Business users can specify field group IDs when they import records into business applications. However, the system assigns a field group ID when you create a field group entry from the user interface.
Source primary key
Source primary keys are unique identifiers of source records and field groups.
When you use ingress jobs to ingress records or use APIs to create or update records, you can specify source primary keys for records. To import data into the MDM SaaS data store, business users use source primary keys to identify records and field group entries.
When you specify source primary keys, perform the following checks:
•The source primary keys of records don't contain a slash (/), backslash (\), period (.), percentage (%), semicolon (;), or double quotation mark (").
The source primary keys can contain the following characters:
~!'={}|:@#$^&*()-_+,<>?`
•The source primary key can contain 255 characters. If the source primary key contains more than 255 characters, the additional characters are truncated.
•The source primary keys of the field groups don't contain special characters other than a colon (:), hyphen (-), pipe (|), or underscore (_).
