3.3 Settlements package update
We have updated the primary key columns SERVICE and CONTRACTID to VARCHAR2(20) in the following tables:
Participants must upgrade to the Data Model v5.7 to receive the data type changes and avoid data load failures after the transition period.
3.3.1 Primary key transition
Transition period: End November 2026 (6 months)
After the Data Model 5.7 production release, we continue to populate the SERVICE and CONTRACTID values with a maximum length of 10 characters until the end of the transition period.
When the transition period ends, if you are using the Data Model v5.6 or earlier, your tables will experience data load failures if the values in the SERVICE or CONTRACTID exceeds 10 characters.
