## Procedures

- `GetCO2eEmissionFromPurchLine(var PurchaseLine: Record "Purchase Line"; var CO2eEmission: Decimal)` (internal)

Plus 15 local procedures.

## 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 6212 "Sustainability Post Mgt"](../codeunit/6212.md) (5 calls: `CheckAndUpdateSustainabilityInvoicePostingBuffer → UpdateCarbonFeeEmissionValues`, `CheckAndUpdateSustainabilityItemChargeAssignmentPurch → UpdateCarbonFeeEmissionValues`, `CheckAndUpdateSustainabilityItemJournalLine → UpdateCarbonFeeEmissionValues`, …)
- [Codeunit 6228 "Sust. Preview Posting Handler"](../codeunit/6228.md) (2 calls: `TryBindPostingPreviewHandler → TryBindPostingPreviewHandler`, `TryUnbindPostingPreviewHandler → TryUnbindPostingPreviewHandler`)
- [Codeunit 5836 "Cost Calculation Management"](../codeunit/5836.md) (1 call: `GetDistributeItemCharge → SplitItemLedgerEntriesExist`)
- [Codeunit 6218 "Sustainability Calc. Mgt."](../codeunit/6218.md) (1 call: `OnValidateQuantityOnBeforeResetAmounts → CalculationEmissions`)
- [Codeunit 6233 "Sust. Preview Post Instance"](../codeunit/6233.md) (1 call: `TryBindPostingPreviewHandler → Initialize`)

## Called by

## 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: "Sust. Purchase Subscriber")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
