Symptoms
Consider the following scenario:
You create a table that has the primary key, and you add some rows to it in Microsoft SQL Server 2019 or 2017.
You add a column that has a default constraint, and you modify the primary key to include the new column.
You create a transactional publication and subscription for this table.
In this scenario, the Distribution Agent fails when it tries to apply UPDATE or DELETE at the subscriber on rows that existed before adding the new column. Additionally, you receive the following "20598" error message:
The row was not found at the Subscriber when applying the replicated UPDATE command for Table 'TableName' with Primary Key(s): (null)
