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 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 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.
