PayablesAgent · Microsoft.Agent.PayablesAgent · BC29-30 · [source at ea08af5e](https://github.com/microsoft/BCApps/blob/ea08af5ef2d6a9b5c5af4a029288abbe2c883220/src/Apps/W1/PayablesAgent/app/Trial/PATrial.Codeunit.al) · facts from BC29

## Properties

| Property | Value |
|---|---|
| Access | Internal |

## Procedures

- `IsEligibleToStart(): Boolean`: Checks whether the current company is eligible to start a trial. Returns true only when no trial has been started and no agent exists in this company.
- `StartTrial()`: Initializes the trial mode by marking trial as started and setting the invoice count to zero.
- `ResetTrial()` (internal)
- `IsActive(): Boolean`: Checks whether the current company is in trial mode and has not exceeded the invoice limit.
- `IncrementTrialInvoiceCount()`: Increments the count of invoices processed during the trial period.
- `GetTrialInvoiceCount(): Integer`: Gets the current count of invoices processed during the trial period.
- `GetTrialInvoiceLimit(): Integer`: Gets the maximum number of invoices allowed during the trial period.
- `MarkTrialEnded()` (internal): Marks the trial as ended at the module (tenant) scope, preventing any company from starting a trial.

## 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 3303 "Payables Agent"](../codeunit/3303.md) (2 calls: `ResetTrial → GetCustomDimensions`, `StartTrial → GetCustomDimensions`)
- [Codeunit 457 "Environment Information"](../codeunit/457.md) (1 call: `IsEligibleToStart → IsProduction`)

## Called by

- [Codeunit 3303 "Payables Agent"](../codeunit/3303.md) (4 calls: `BuildAgentTask → GetTrialInvoiceCount`, `BuildAgentTask → GetTrialInvoiceLimit`, `BuildAgentTask → IncrementTrialInvoiceCount`, …)
- [Codeunit 3307 "Payables Agent Setup"](../codeunit/3307.md) (2 calls: `InitializeTrialIfEligible → IsEligibleToStart`, `InitializeTrialIfEligible → StartTrial`)

## 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: "PA Trial")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
