# Codeunit 2679 "Purchase Alloc. Acc. Mgt."

> Codeunit 2679 "Purchase Alloc. Acc. Mgt." in Base Application (Microsoft.Finance.AllocationAccount.Purchase). 7 public procedures, 3 events, 5 event subscribers. Present since at least BC23, still in BC30, changed in BC24-25, BC27-28.

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

## Events published

- `OnBeforeCreatePurchaseLine(var PurchaseLine: Record "Purchase Line"; var AllocationLine: Record "Allocation Line"; var AllocationPurchaseLine: Record "Purchase Line")` (integration): Integration event raised before creating purchase line from allocation line during distribution process. Enables custom modification of purchase line fields before standard allocation line processing.
- `OnBeforeVerifyPurchaseLine(var PurchaseLine: Record "Purchase Line")` (integration): Integration event raised before verifying purchase line during allocation account validation. Enables custom validation logic for purchase lines before standard allocation verification.
- `OnLoadManualAllocationLinesOnBeforeInsertAllocationLine(var AllocAccManualOverride: Record "Alloc. Acc. Manual Override"; var AllocationLine: Record "Allocation Line")` (integration)

## Event subscriptions

- HandlePostDocument subscribes to Codeunit "Purch.-Post" OnBeforePostPurchaseDoc
- HandleShowDimensions subscribes to Table "Purchase Line" OnBeforeShowDimensions
- HandleAfterCheckSalesApprovalPossible subscribes to Codeunit "Approvals Mgmt." OnAfterCheckPurchaseApprovalPossible
- CheckBeforeModifyLine subscribes to Table "Purchase Line" OnBeforeModifyEvent
- HandleValidateLineNo subscribes to Table "Purchase Line" OnBeforeValidateNo

## Procedures

- `GetOrGenerateAllocationLines(var AllocationLine: Record "Allocation Line"; var ParentSystemId: Guid)` (internal)
- `GetOrGenerateAllocationLines(var AllocationLine: Record "Allocation Line"; var ParentSystemId: Guid; var AmountToAllocate: Decimal; var PostingDate: Date)` (internal)
- `LoadManualAllocationLines(var PurchaseLine: Record "Purchase Line"; var AllocationLine: Record "Allocation Line")` (internal)
- `CreateLinesFromAllocationAccountLine(var AllocationAccountPurchaseLine: Record "Purchase Line")`: Creates individual purchase lines from allocation account distribution lines based on allocation percentages or amounts. Processes allocation account configuration and generates corresponding G/L account lines with calculated amounts.
- `VerifyAllocationAccount(var AllocationAccount: Record "Allocation Account")` (internal)
- `TransferDimensionSetID(var PurchaseLine: Record "Purchase Line"; var AllocationLine: Record "Allocation Line"; ModifiedByUser: Boolean)`: Transfers dimension set ID from allocation line to purchase line with merge capabilities. Combines dimensions when both records have existing dimension sets or overwrites when specified.
- `VerifySelectedAllocationAccountNo(var PurchaseLine: Record "Purchase Line")`: Validates the selected allocation account number on purchase line and verifies compatibility. Ensures the allocation account is properly configured and the purchase line uses G/L account type.

Plus 23 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.

## 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: "Purchase Alloc. Acc. Mgt.")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
