## Properties

| Property | Value |
|---|---|
| TableNo | GP Vendor |
| Permissions | tabledata "Standard Purchase Code" = RIM, tabledata "Standard Purchase Line" = RIM, tabledata "Standard Vendor Purchase Code" = RIM |

## Event subscriptions

- OnMigrateVendor subscribes to Codeunit "Vendor Data Migration Facade" OnMigrateVendor
- OnMigrateVendorPostingGroups subscribes to Codeunit "Vendor Data Migration Facade" OnMigrateVendorPostingGroups
- OnMigrateVendorTransactions subscribes to Codeunit "Vendor Data Migration Facade" OnMigrateVendorTransactions

## Procedures

- `MigrateVendorTransactions(var Sender: Codeunit "Vendor Data Migration Facade"; RecordIdToMigrate: RecordId; ChartOfAccountsMigrated: Boolean)`
- `ShouldMigrateVendor(VendorNo: Text[75]; var IsTemporaryVendor: Boolean; var HasOpenPurchaseOrders: Boolean; var HasOpenTransactions: Boolean): Boolean` (internal)
- `PopulateStagingTable(JArray: JsonArray)`
- `PopulateVendorStagingTable(JArray: JsonArray)`
- `MigrateVendorEFTBankAccounts()`

Plus 21 local procedures.

## Relations

- runs on [Table 4096 "GP Vendor"](../table/4096.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 6111 "Vendor Data Migration Facade"](../codeunit/6111.md) (33 calls: `CreateRecurringPurchaseLines → DoesVendorExist`, `MigrateEmailAddresses → SetEmail`, `MigrateVendorAddresses → DoesVendorExist`, …)
- [Codeunit 4037 "Helper Functions"](../codeunit/4037.md) (24 calls: `CreateOrUpdateOrderAddress → CleanGPPhoneOrFaxNumber`, `CreateOrUpdateRemitAddress → CleanGPPhoneOrFaxNumber`, `CreateRecurringPurchaseLineImp → CreateDimSet`, …)
- [Codeunit 1796 "Data Migration Error Logging"](../codeunit/1796.md) (4 calls: `MigrateVendorEFTBankAccounts → SetLastRecordUnderProcessing`, `MigrateVendorTransactions → SetLastRecordUnderProcessing`, `OnMigrateVendor → SetLastRecordUnderProcessing`, …)
- [Codeunit 1797 "Data Migration Facade Helper"](../codeunit/1797.md) (1 call: `MigrateVendorTransactions → CreateSourceCodeIfNeeded`)
- [Page 456 "No. Series"](../page/456.md) (1 call: `CreateRecurringPurchaseLineImp → (object)`)

## Called by

- [Codeunit 4037 "Helper Functions"](../codeunit/4037.md) (2 calls: `CreateVendorEFTBankAccountsImp → MigrateVendorEFTBankAccounts`, `GetNumberOfVendors → ShouldMigrateVendor`)

## Across versions

- Present in: BC29-30
- Changed (declaration) in: none

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: "GP Vendor Migrator")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
