Step 2: Select a table

A search dialog appears. Type the name of the table you want to investigate and select it from the results.

Step 3: Read the call graph

The view shows all objects that access the selected table, organized into a call graph from entry point to the table. This shows the full chain: which transactions touch the table, through which objects.

Step 4: Identify data ownership

If many different modules or transactions access the same table, the data is shared. Shared data is harder to migrate independently.

Use tags to mark the objects or the table for follow-up. See Tag objects, transactions, and modules.
