Data Lineage

Data Lineage traces a DB2 column, IMS segment field, or file field through COBOL host variables, copybooks, and related programs. Open it from table metadata, an IMS segment or CBLTDLI I/O area, or a field-specific connection detail.

The tree shows field type, source, data type, usage category, line numbers, and hierarchy. Expand nodes lazily, select a usage to preview nearby source, and use Open to jump to the full Source Viewer.

Use Track on a COBOL variable to locate usages across the program and resolved copybooks. Results classify SQL, MOVE, arithmetic, string, file I/O, DL/I (GET, ISRT, REPL, DLET, PCB), calls, conditions, display, acceptance, and declarations, including assignment and REDEFINES relationships.
