Trace a DB2 column before we change the copybook

We are about to change a copybook field. How do we see which programs move that value before we edit?

Start from the field, not from a program name. [[product:ol-atomiq|OL AtomIQ]] data lineage follows a DB2 column, an IMS segment, or a file field through COBOL host variables, across programs and copybooks. That is the impact picture you want before the edit. A call graph alone will not show you the field.
