Base Application · System.Email · BC23-30 · [source at ea08af5e](https://github.com/microsoft/BCApps/blob/ea08af5ef2d6a9b5c5af4a029288abbe2c883220/src/Layers/W1/BaseApp/OtherCapabilities/Email/EmailAddressLookup.PageExt.al) · facts from BC29

Extends [Email Address Lookup](../page/8944.md).

## Fields on this page

Layout controls in source order, grouped by the container they sit in. Shows: the table field a control is bound to (or its expression as written); ToolTip: the control's own, else the bound field's (marked).

| Group | Control | Shows | ToolTip |
|---|---|---|---|
| Contact filters | Job Responsibility | `JobSelection` | A comma separated list of Job Responsibility codes. |

## Actions

| Group | Action | ToolTip | Runs |
|---|---|---|---|
| addbefore(Users) | Contacts | Add addresses from Contacts. |  |
|  | Customers | Add addresses from Customers. |  |
|  | Vendors | Add addresses from Vendors. |  |
|  | Employees | Add addresses from Employees. |  |

## Procedures

- `GetContactsFilter(var Responsibility: Record "Job Responsibility"): Text` (internal)

## Relations

- extends [Page 8944 "Email Address Lookup"](../page/8944.md)

## 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 46 "SelectionFilterManagement"](../codeunit/46.md) (1 call: `GetContactsFilter → GetSelectionFilter`)

## Called by

- [Codeunit 8906 "Email Editor"](../codeunit/8906.md) (2 calls: `LookupRecipients → (object)`, `PopulateRelatedRecordCache → (object)`)
- [Codeunit 8944 "Email Address Lookup Impl"](../codeunit/8944.md) (1 call: `LookupEmailAddress → (object)`)

## Across versions

- Present in: BC23-30
- Changed (declaration) in: none

Source: AL metadata extracted from the code (names, ids, signatures, properties); no code bodies (D10).

## 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: "pageextension", object_name: "Email Address Lookup")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
