create a view in sap datasphere for the below requirement Stock Metrics will be calculated based on - Current month (Actuals) + forecast to next 3 months Forecast for current month (projected month end stock value) = Opening stock of the current month

Creating a view in SAP Datasphere (formerly known as SAP Data Warehouse Cloud) involves a few steps and requires access to both the data model and the query tools. Below is a guide to creating a view that calculates stock metrics based on your requirements. ### Step-by-Step Guide to Create the View #### 1. **Data Preparation** Ensure you have access to the following tables or data sources: - **Stock Data**: This table should include Opening Stock, Pending Arrivals, and BTG Forecast data. - **Calendar Table**: This may be needed to determine the current and projected months if you want to parameterize the view dynamically. #### 2. **Create a New View** 1. **Log in to SAP Datasphere**: Access your SAP Datasphere environment. 2. **Navigate to the Modeling Section**: Go to `Models` and click on `New Model`. 3. **Select View Type**: Choose `Calculation View` as the view type. 4. **Define Data Sources**: Add your necessary data sources (tables) into the view. #### 3. **Define Required Calculations** ##### A. **Current Month Metrics** - **Calculate Forecast for Current Month**: - This can be achieved using the formula: \[ \text{Forecast Current Month} = \text{Opening Stock} + \text{Pending Arrivals} - \text{BTG Forecast} \] - **Create Calculated Column**: - Name: `Forecast_Current_Month` - Formula: ```sql OPENING_STOCK + PENDING_ARRIVALS - BTG_FORECAST ``` ##### B. **Next 3 Months Projected Metrics** - **Calculate Projected Stock Value for Next 3 Months**: - You might want to set up a loop or a union to calculate for each of the next three months if you're dealing with multiple records. - Assuming you are structuring this in a simple calculation: ```sql Projected_Stock_Month_1 = PENDING_ARRIVALS_M1 - BTG_FORECAST_M1 Projected_Stock_Month_2 = PENDING_ARRIVALS_M2 - BTG_FORECAST_M2 Projected_Stock_Month_3 = PENDING_ARRIVALS_M3 - BTG_FORECAST_M3 ``` - **Create Columns for Each Month**: - Names: `Projected_Stock_Month_1`, `Projected_Stock_Month_2`, `Projected_Stock_Month_3` - Formulas: ```sql PENDING_ARRIVALS_M1 - BTG_FORECAST_M1 PENDING_ARRIVALS_M2 - BTG_FORECAST_M2 PENDING_ARRIVALS_M3 - BTG_FORECAST_M3 ``` #### 4. **Combine Results** - Now that you’ve calculated metrics for the current month and the next three months, you may want to create another calculated column that aggregates these metrics depending on your reporting needs. #### 5. **Save and Activate the View** - Once you have defined all your calculations, save the view and activate it. ### Final Considerations - **Testing**: Validate the view with sample data to ensure it returns the expected results. - **Performance**: Consider performance implications for large datasets; optimization might be needed based on the size of the tables used. - **Documentation**: Document the logic and any assumptions made during the view creation for future maintenance and clarity. This is a high-level overview and implementation can vary based on specific business rules, data formats, and available tools within SAP Datasphere. Ensure you adapt the details to fit your actual data schema.
