As your tutor, I want you to think of the POV (Point of View) as the GPS Coordinates for your data. In Excel, you have A1 or B2. In EPM, a cell doesn't exist until you define every single dimension.
1. The Definition: Cell Intersections
In an EPM application, data is stored at the intersection of all dimensions.
* The Intersection: If your cube has 10 dimensions, every data point is the result of 10 members meeting at a single point.
* The POV: This is the 'context' of your data. It represents the dimensions that are held constant while you analyze rows and columns.
2. The "GPS & Skyscraper" Example
Imagine you are meeting a friend in a massive skyscraper.
* The Address: If you only say "Room 402," your friend is lost. Which City? Which Building? Which Floor?
* The POV:
* City: New York (POV)
* Building: Empire State (POV)
* Floor: 4th (POV)
* Intersection: Room 402.
In Essbase, 'New York' and 'Empire State' are your POV. They define the 'where' and 'when' so that your 'Sales' numbers make sense.
3. How it is useful while building an application
* Data Loading: You cannot load '100' into the system. You must load '100' into 'Actual -> 2024 -> Jan -> New York -> Sales'. Without the full POV, the data has no home.
* Reporting: You can build one single 'Profit & Loss' report and use the POV to let users switch between 'London' and 'Paris' instantly.
* Security: You can lock a user's POV so they can only see their own department's coordinates.
4. Where do we use these concepts?
* Smart View: Using the POV bar to filter and slice data.
* Calc Scripts: Using the 'FIX' command to tell the engine: "Only calculate the 'Actual' POV."
* Forms: Designing templates where the Year and Scenario are fixed in the background (The POV).
5. Extra Information: The "Missing Link"
If you ever see #Missing in a report when you know there is data, 99% of the time, your POV is wrong. You might be looking at 'Actuals' for a month where data hasn't been loaded yet. Always check your GPS coordinates first!
