An activity has 100 hours work and you have already confirmed 30 hours. If next time you confirm :

• A degree of processing of 50%, the system sets the actual work to 20 hours and the remaining work to 50 hours.
• A degree of processing of 10%, the system sets the actual work to 0 hours and the remaining work to 270 hours.

If the degree of processing is larger than that in the last confirmation, the system presumes that processing is going as planned and calculates the work done since the last confirmation and the remaining work.

If you enter a smaller degree of processing than the proportion of the planned work and the work already completed, the system interprets this as meaning that the remaining work has increased. The system calculates this remaining work from the actual work and the degree of processing you entered.
