System Application · System.Reflection · BC23-30 · [source at ea08af5e](https://github.com/microsoft/BCApps/blob/ea08af5ef2d6a9b5c5af4a029288abbe2c883220/src/System%20Application/App/Field%20Selection/src/FieldSelection.Codeunit.al) · facts from BC29

## Properties

| Property | Value |
|---|---|
| Access | Public |

## Procedures

- `Open(var SelectedField: Record "Field"): Boolean`: Opens the fields lookup page and assigns the selected fields on the parameter.

## Calls

From the extracted call graph of BC29 (graphify-al on the snapshot checkout): calls whose target is known from a declared type or an `Object::"Name"` argument. Interface dispatch and calls through events are not counted, so the list is not complete.

- [Codeunit 9807 "Field Selection Impl."](../codeunit/9807.md) (1 call: `Open → Open`)

## Ask your agent

Procedure bodies are not stored here (D10). The call sections above are our own, per object, from the BC29 call graph. For a procedure body or the calls of one procedure, ask bc-code-atlas (external, by Stefan Maron, MIT; default corpus w1-28), which the bc-observatory plugin connects: `bcatlas_resolve_node(object_type: "codeunit", object_name: "Field Selection")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
