AuditTableProcessing Question from Microsoft Data Warehouse Toolkit. Audit Dimension

In this book, the authors recommend 3 tables for an auditing.

The second table gets a new row for each table that is manipulated in a package. It consists of columns like ExtractRowCount, InsertStndRowCnt, UpdateRowCnt, etc.

However, if I am splitting my process into phases like Extract, Transform, and Load with staging between them, what exactly is my TableName?

I think that it would be the Source Table Name for the Extract, Staging Source Table Name for the Transform, and the Destination Table for the Load.

However, if I do that, how do I tie all of my records together to verify that I've accounted for every row extracted in some way?
