Confirmation Directly in the Project
System 
You can use this function to make confirmations in the Project System(PS).
You can only confirm activities and activity elements, if
· these activities and activity elements have the status “Released”
· the confirmation indicator has been set in the control key
You must have defined certain confirmation parameters in Customizing for the Project System previously. Here you specify in Confirmation ® Define confirmation parameters, for instance, how much the confirmed work or duration may differ from the values planned in the activity and whether a workflow is triggered if this margin is exceeded. You can change some of these parameters during confirmation.
You enter confirmation in the following ways:
· For each activity, activity element or individual capacity
· For a network
· As a collective confirmation
· As a summary confirmation
You can enter the following data during confirmation:
· Actual dates
· Actual durations
· Work done
· Reason for variance
· Forecast values for the remaining work and the remaining duration
· Indicator for the confirmation status.
If you enter a personnel number in the confirmation, the system creates a data record for Time Management, which can be processed further when you enter incentive wages or by using report program RPWI0010 (Batch Input for activity wages).
When you confirm an activity that has material components assigned to it that are to be backflushed, the system automatically posts the goods issue for these components. If the goods cannot be issued, you receive, depending on the confirmation parameters in Customizing, an error message or an error log. You can reprocess goods issues that have errors and:
· Change goods issued processed by backflushing
· Carry out planned material issues (depending on the settings you made in Customizing for confirmation parameters)
· Carry out unplanned material issues
By confirming an activity you can trigger milestone functions or a workflow. See Triggering Milestone Functions and Triggering Workflows.
You can also create a pool of confirmations, which you can use for further confirmations. See Creating a Pool of Confirmations.
After you have saved the confirmation, the system
· Posts your confirmation for the date entered
· Copies the actual dates to the network or WBS element
· Calculates the actual costs for the posting date
· Provides data from the Personnel Administration (HR) application component for calculating incentive wages and absence/attendance
· Posts any goods withdrawal or issues a message if a goods withdrawal is not possible
· Triggers milestone functions, if required.
According to your settings in Customizing, the
system executes these activities immediately or later in a background job
(improving the performance). For more information, see
Decoupling Processes
Carried out During Confirmation
You have to reprocess error issues that have errors, if any have occurred.

When you save confirmations, the networks are not rescheduled and they do not receive the Dates are not updated status.
