- `OnBeforeInsertLineForTotalDocumentAmount(EntryNo: Integer; var IsHandled: Boolean)` (integration)
- `OnBeforeProcessLine(EntryNo: Integer; HeaderRecordNo: Integer; RecordNo: Integer; VendorNo: Code[20]; var IsHandled: Boolean)` (integration)

- `FindAppropriateGLAccount(EntryNo: Integer; HeaderRecordNo: Integer; LineDescription: Text[250]; LineDirectUnitCost: Decimal; VendorNo: Code[20]): Code[20]`

Plus 42 local procedures.

## 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 1251 "Record Match Mgt."](../codeunit/1251.md) (3 calls: `FindVendorByNameAndAddress → CalculateStringNearness`, `FindVendorByPhoneNo → CalculateStringNearness`, `ValidateCompanyInfoByNameAndAddress → CalculateStringNearness`)

## Called by

- [Codeunit 1218 "Map Incoming Doc to Purch Doc"](../codeunit/1218.md) (1 call: `CreateInvoiceChargePurchaseLine → FindAppropriateGLAccount`)
- [Codeunit 1224 "Map Incoming Doc to Gen. Line"](../codeunit/1224.md) (1 call: `GetAttachedDocumentType → ConstructDocumenttypeUnknownErr`)

## Across versions

- Present in: BC23-30
- Changed (declaration) in: BC24-25

## Countries that replace it

[AU](../../localizations/au.md), [NZ](../../localizations/nz.md)

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: "Pre-map Incoming Purch. Doc")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
