Understanding Subscription Number (csordtelcoa__Subscription_Number__c) Generation Logic

Symptom

How are Subscription Numbers generated? What determines the format and sequence of csordtelcoa__Subscription_Number__c?

Cause

N/A (informational)

Resolution

Generation logic

Subscription Numbers are system-generated incremental numbers with the following characteristics:

• Format: {000000000} (9 digits, zero-padded)
• Source: Salesforce auto-increments for each new Subscription record
• Sequence: The number depends only on the last assigned number, not on year, product definitions, or other factors

Prefix configuration

The prefix is configurable via Custom Settings:

• Custom Setting: Orders_Subscriptions_Options__c.Subscription_Number_Prefix__c
• Default prefix: SN-

Change Order behavior

On a Change Order where the product definition record type stays the same, the subscription number is inherited from the replaced subscription and is not regenerated.

How the Number Is Generated

When a new Subscription record is created, the system automatically generates the subscription number by concatenating the configured prefix (default SN-) with a Salesforce auto-number field (Subscription_Number_Sequence__c, format {000000000}).

On change orders, if the replaced subscription's product definition record type matches the new one, the number is inherited from the replaced subscription. Otherwise, a new number is generated.

Additional Notes

• To change the prefix, update the Subscription_Number_Prefix__c field in the Orders_Subscriptions_Options__c custom setting.
• The 9-digit sequence is independent of any other attributes; it is purely sequential based on the last assigned number.
