# Codeunit 4312 "Agent Session"

> Codeunit 4312 "Agent Session" in System Application (System.Agents). 2 public procedures. Introduced in BC26, still in BC30, changed in BC27.

System Application · System.Agents · BC26-30 · [source at ea08af5e](https://github.com/microsoft/BCApps/blob/ea08af5ef2d6a9b5c5af4a029288abbe2c883220/src/System%20Application/App/Agent/Interaction/AgentSession.Codeunit.al) · facts from BC29

## Procedures

- `IsAgentSession(var ActiveAgentMetadataProvider: Enum "Agent Metadata Provider"): Boolean`: Checks if the current session is an agent session.
- `GetCurrentSessionAgentTaskId(): BigInteger`: Get the agent task ID related to the current session, if any, -1 otherwise.

## Called by

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 3303 "Payables Agent"](../codeunit/3303.md) (2 calls: `IsPayablesAgentSession → GetCurrentSessionAgentTaskId`, `IsPayablesAgentSession → IsAgentSession`)
- [Codeunit 4420 "SOA Task Message Reader"](../codeunit/4420.md) (2 calls: `GetLastIncomingMessageContent → GetCurrentSessionAgentTaskId`, `GetLastIncomingMessageContent → IsAgentSession`)
- [Codeunit 3311 "PA Billing"](../codeunit/3311.md) (1 call: `LogPurchaseDocumentDraftLinesProcessed → GetCurrentSessionAgentTaskId`)
- [Codeunit 4323 "SOA Awareness Notifications"](../codeunit/4323.md) (1 call: `IsBindingNeeded → IsAgentSession`)
- [Codeunit 4360 "Custom Agent Session"](../codeunit/4360.md) (1 call: `IsCustomAgentSession → IsAgentSession`)
- [Codeunit 4595 "SOA - KPI Track All"](../codeunit/4595.md) (1 call: `UpdateEntry → GetCurrentSessionAgentTaskId`)
- [Codeunit 4598 "SOA Instructions"](../codeunit/4598.md) (1 call: `AddCultureToBroaderItemSearchSystemPrompt → GetCurrentSessionAgentTaskId`)
- [Codeunit 6908 "Expense Event Subscriber"](../codeunit/6908.md) (1 call: `ValidateExpenseAgentLoginNotAllowed → IsAgentSession`)

## Across versions

- Present in: BC26-30
- Changed (declaration) in: BC27

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: "codeunit", object_name: "Agent Session")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
