## Triggers

OnRun

## Relations

- runs on [Table 1220 "Data Exch."](../table/1220.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 66 "Purch - Calc Disc. By Type"](../codeunit/66.md) (2 calls: `ApplyInvoiceDiscounts → ApplyInvDiscBasedOnAmt`, `ApplyInvoiceDiscounts → InvoiceDiscIsAllowed`)
- [Codeunit 1217 "Pre-map Incoming Purch. Doc"](../codeunit/1217.md) (1 call: `CreateInvoiceChargePurchaseLine → FindAppropriateGLAccount`)
- [Codeunit 1224 "Map Incoming Doc to Gen. Line"](../codeunit/1224.md) (1 call: `OnRun → (object)`)
- [Codeunit 57 "Document Totals"](../codeunit/57.md) (1 call: `VerifyTotals → PurchaseCalculateTotalsWithInvoiceRounding`)
- [Codeunit 8617 "Config. Validate Management"](../codeunit/8617.md) (1 call: `SetFieldValue → EvaluateValueWithValidate`)

## Across versions

- Present in: BC23-30
- Changed (declaration) in: BC26

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: "Map Incoming Doc to Purch Doc")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
