In SAP Datasphere, there are several ways to create a local table with a custom name, providing flexibility for data management. Two common methods are by importing a CSV file and by adding an output of a data flow. When you import a CSV file, Datasphere allows you to specify a custom name for the new local table that will store the imported data. This is a quick and straightforward way to bring external, flat-file data into Datasphere. Secondly, a data flow in Datasphere allows you to define a sequence of operations (e.g., transformations, aggregations) and write the processed data to a target. When configuring the output of a data flow, you can specify a new local table and provide it with a custom name. This method is ideal for creating structured tables as a result of complex data integration or transformation processes. These options ensure that users can create and name tables according to their specific data modeling and organizational requirements.

To leverage version management capabilities within an SAP Analytics Cloud (SAC) story, it is a fundamental requirement that the story is built on a planning model. Version management is a core feature specifically designed for planning functionalities. It enables users to create, manage, and compare different scenarios or iterations of data, such as 'Actual,' 'Budget,' 'Forecast,' or various planning versions. This is critical for budgeting, forecasting, and what-if analysis, allowing planners to work on different data sets concurrently and track changes over time. While analytic models are used for general reporting and analysis, they do not inherently support the robust version management features that are integral to planning processes. Therefore, if you intend to utilize version management to compare different data scenarios or manage planning cycles, your SAC story must be connected to a planning model.

When an SAP Analytics Cloud (SAC) story is based on an import model, the data is physically copied and stored within SAC. Therefore, simply refreshing the story (option A) will only update the visualization with the data already in the model and will not pull new data from the source. Similarly, 'Allow model import' (option B) isn't a direct action for updating data, but rather a prerequisite for the import process itself. 'Refresh the data source' (option C) is not an action performed within SAC for an import model. To update the data in the model when the transactional data in its source changes, you must schedule the import (option D) or manually re-run the import process. This process re-fetches the latest data from the original source system and updates the SAC import model, ensuring your story reflects the most current information. This scheduling can be set up to occur at regular intervals, keeping the model synchronized with the source data.

C . Create an SQL view with a JOIN operation

SQL views in Datasphere allow you to write SQL code directly.

You can use JOIN in your SQL script to combine multiple artifacts (tables/views).

SELECT a.CustomerID, b.SalesAmount

FROM Customers a

JOIN Sales b ON a.CustomerID = b.CustomerID;

D . Create a graphical view, drag an artifact to the canvas, and the second one on top of the first one

In the Datasphere graphical modeler, when you drag the second artifact onto the first one, the system automatically creates a Join node.

You can then define the join type (Inner, Left Outer, Right Outer, Full).

This is the drag-and-drop method for joins.
