    ResponseNamespace = "https://schemas.microsoft.com/office/project/server/webservices/QueueSystem/",

public void UnblockCorrelation(
    Guid correlationGUID
)

Parameters

• correlationGUID
  Type: System.Guid
  GUID of the correlation.

Remarks

If the job state is not CorrelationBlocked, UnblockCorrelation generates a SOAP exception.

UnblockCorrelation sets the state of the blocked job to FailedNotBlocking and sets the other blocked jobs in the correlation from CorrelationBlocked to ReadyForProcessing.

Warning

The Project Server Queuing Service blocks a correlation to prevent corruption of data. Arbitrarily unblocking a correlation can produce undesired results. Use UnblockCorrelation only if you are confident the remaining jobs behind the blocked job can proceed without harm.

A Project Server administrator can use the Manage Queue Jobs page in Project Web App (https://ServerName/ProjectServerName/_layouts/pwa/Admin/queue.aspx) to view and unblock correlated jobs.
