The service forwards the requests to the application server identified by the “serverName” input. See [SupportedAdjustmentsService](https://docs.activeviam.com/products/modules/adjustments-services/4.1/online-help/overview/adjustment-services.html#supportedadjustmentsservice) in the Atoti Adjustments Services documentation for details about the service on the application server side. ### DTOs | DTO | Description | | ---------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | | TypedFieldDTO | Data object containing a field name and a type. | | LevelTypedFieldDTO | Extension of the TypedFieldDTO object, with an added levelPath property. | | SupportedAdjustmentDTO | Data object for the definition of the supported adjustment. Holds information about: \* The stores the adjustment applies to \* Required filters (as a set of LevelTypedFieldDTO) \* Supported measures \* Required inputs (as a set of TypedFieldDTO) | ## Adjustment execution Interfaces and implementations to allow the submission of adjustments requests. ### ISignOffAdjustmentExecutionService interface An interface providing an adjustment execution endpoint which returns an execution ID for use with the status service. ### SignOffAdjustmentExecutionService An implementation of the `ISignOffAdjustmentExecutionService` interface. The service forwards the requests to the application server identified by the “serverName” field in the AuditableAdjustmentRequestDTO object. See [AdjustmentExecutionService](https://docs.activeviam.com/products/modules/signoff-api/1.5.0/online-help/overview/signoff_ext-module.html#adjustmentexecutionservice) in the Atoti Sign-Off API documentation for details about the service on the application server side. ### DTOs | DTO | Description | | ----------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | NamedValueDTO | Data object containing a name and a value. | | AuditableAdjustmentRequestDTO | Request object defining: \* The server name to which the execution request is sent \* The key of the adjustment type \* The user and task for which the adjustment is requested \* A set of NamedValueDTO filters \* A set of measures for which the adjustment applies and the required input (as a set of NamedValueDTO) . | ## Execution status Interfaces and implementations that publish the status of a given adjustment request. ### ISignOffAdjustmentStatusService interface An interface containing an endpoint for the retrieval of the status of an execution task. ### SignOffAdjustmentStatusService An implementation of the `ISignOffAdjustmentStatusService` interface. The service forwards the requests to the application server identified by the "serverName" field in the AuditableAdjustmentRequestDTO object. See [AdjustmentStatusService](https://docs.activeviam.com/products/modules/signoff-api/1.5.0/online-help/overview/signoff_ext-module.html#adjustmentstatusservice) in the Atoti Sign-Off API documentation for details about the service on the application server side. ### DTOs | DTO | Description | | ------ | ---------------------------------------------------------------------------- | | Status | An enum object holding the status of an execution task for the execution Id. | ### The status enum The Status `Enum` provides a set of possible statuses for an execution: * Requested * Pending * Executed * Failed * Cancelled * Deleting * Deleted ## Further reading ### REST services All adjustment services are also wrapped in REST services for interoperability.
