Base Application · Microsoft.Sales.Customer · BC23-30 · [source at ea08af5e](https://github.com/microsoft/BCApps/blob/ea08af5ef2d6a9b5c5af4a029288abbe2c883220/src/Layers/W1/BaseApp/Sales/Customer/TopTenCustomersChartMgt.Codeunit.al) · facts from BC29

## Procedures

- `UpdateChart(var BusChartBuf: Record "Business Chart Buffer")`: Updates the business chart buffer with the top ten customers by sales data for stacked column chart visualization.
- `DrillDown(var BusChartBuf: Record "Business Chart Buffer")`: Handles drill-down actions on the top ten customers chart by opening the customer card or customer list.

Plus 4 local procedures.

## Triggers

OnRun

## 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 1315 "Chart Management"](../codeunit/1315.md) (1 call: `CalcTopTenSalesCustomers → ScheduleTopCustomerListRefreshTask`)
- [Codeunit 1328 "Top Customers By Sales Job"](../codeunit/1328.md) (1 call: `CalcTopTenSalesCustomers → UpdateCustomerTopList`)
- [Page 21 "Customer Card"](../page/21.md) (1 call: `DrillDownCust → (object)`)

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: "Top Ten Customers Chart Mgt.")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
