Execution details
Functional workflow
Executing an adjustment should conform to the following steps:
| Step | Details |
|---|---|
| Retrieve supported adjustments from the appropriate REST endpoint | The adjustment requests need to conform to the specification returned by the supported adjustments service, but once the requests are created, this step isn’t necessary. |
| Initiate the sign-off task | The status of of the sign-off process for the filters defined in the association sign-off task is set to ‘INITIATED’. |
| Request adjustment. | Adjustment requests will be executed asynchronously on the sign-off snapshot. There is no limit to the number of adjustments that can be requested for a snapshot. |
| Approve the sign-off task | The status of of the sign-off process for the filters defined in the association sign-off task is set to ‘APPROVED’. |
| Retrieve the status of an adjustment execution | As adjustments are executed asynchronously, a service is provided for retrieving the status of a given adjustment execution. Any errors in the execution of an adjustment will result in a FAILED status being returned by the status service. |
