What is the difference between milestones and activities in SAP PS?

In SAP Project System (PS), milestones and activities are key elements used for project planning and tracking. Here is the difference between milestones and activities in SAP PS:

Milestones:

• Milestones represent significant events or checkpoints in a project that mark the completion of a key deliverable or phase.
• Milestones are used to track progress and measure the achievement of project goals.
• Milestones have zero duration and signify a specific point in time within the project schedule.
• Milestones are displayed as diamonds in the project network diagram.

Activities:

• Activities are the tasks or work packages that need to be completed to achieve project objectives.
• Activities have a defined duration and are the building blocks of a project schedule.
• Activities are linked together in a logical sequence to determine the project timeline and dependencies.
• Activities are displayed as rectangles in the project network diagram.

In conclusion, milestones represent key project events or achievements, while activities are the detailed tasks that make up the project work. Both milestones and activities play a crucial role in project planning and tracking in SAP PS.
