## Procedures

- `IsLegacySubcontractingEnabled(): Boolean` (internal): Returns whether Legacy Subcontracting is enabled in Manufacturing Setup.
- `CheckCanDisableLegacySubcontracting()`: Checks whether Legacy Subcontracting can be disabled and raises an error if the preconditions are not met. When a required app is missing, it offers to install it inline.
- `CanDisableLegacySubcontracting(): Boolean` (internal): Checks whether Legacy Subcontracting can be disabled and raises an error if the preconditions are not met. When a required app is missing, it offers to install it inline and returns false so the caller does not disable Legacy Subcontracting - after the install completes and the session reloads, the ...
- `CheckCanEnableLegacySubcontracting()`: Checks whether Legacy Subcontracting can be enabled and raises an error if the preconditions are not met.
- `DatabaseHasLegacySubcontractingData(): Boolean` (internal): Returns whether the database contains Legacy Subcontracting data based on the presence of subcontracting purchase orders, subcontracting transfer orders, WIP Item related data, capacity ledger entries, or subcontracting prices.
- `MigrateData()` (internal)
- `SetLegacySubcontracting(var ManufacturingSetup: Record "Manufacturing Setup"; Enabled: Boolean)` (internal)

## Ask your agent

Procedure bodies are not stored here (D10). 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: "Legacy Subc. Feature Handler")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.

A IT country object, not part of W1: the default corpus does not have it; `bcatlas_list_countries` shows which countries the atlas has.
