Explore - Fields Tab
The Fields tab lists SQL columns and how programs use them. Many analysts treat this as the fastest path from a table to the variables and modules that read or update specific columns.
Field grid
Each row is one field (column). Use search to find a column by name.
Filters
- By table — Show only fields for one table (common research path: pick the table, then scan every column the application touches).
- By module — Show only fields that a specific program uses.
Combining focusing on (one table) with field-level detail avoids hunting module-by-module when you already know the data model.
Field detail
Select a field to see:
- What action each usage performs (read, write, insert, update, and similar)
- Links to the table for broader context
- Links to the variable that participates in the program logic (COBOL, RPG, or other ingested language)
Follow the variable link when you need to see assignments, group structure, or paragraph- or subroutine-level usage.
Typical workflow — one table
- Filter the grid to your table.
- Scan fields of interest (keys, amounts, status codes).
- Open a field → note the module and variable.
- Continue on the Variables or Modules tab for lineage inside the program.
Typical workflow — same field name across tables
Many legacy schemas reuse column names—account ID, branch code, status, and similar keys appear on multiple tables.
- Search the Fields tab by field (column) name without filtering to a single table.
- Review every table that exposes that column and which modules read or write each usage.
- Open field detail for each hit to compare actions (read vs write) and linked variables.
This helps when you care about a key or domain concept that spans reporting tables, not just one table’s full column list.
