SAC Dimension Load Data

In SAP Analytics Cloud (SAC), to load data into a dimension from a file, you can follow these steps. SAC allows you to manage dimensions for your models, either importing data directly or managing dimensions separately from a file (like a CSV).

Here's how you can do it:

Steps to Load Data into a Dimension from a File in SAC:

1. Prepare Your File

Ensure your file (CSV or Excel) is formatted correctly with the data that matches the structure of your dimension in SAC. If you are adding to an existing dimension, make sure you have the correct unique identifiers for your records.

2. Navigate to the Model

• In SAC, go to the Modeler by clicking on the hamburger menu (☰) in the top-left corner.
• Select Modeler and choose the model that contains the dimension you want to update.

3. Open Dimension Management

• In the Modeler, go to the Dimensions tab.
• Select the dimension you want to update or add records to (e.g., Product Dimension).

4. Import Data from a File

• Click on the Import Data button for the dimension.
• Choose Import from a File.
• Upload your CSV or Excel file.

5. Map the Fields

• After uploading the file, SAC will prompt you to map the fields from your file to the fields in your dimension.
• Ensure that each column from your file is correctly mapped to the appropriate field in the dimension (e.g., Product_ID to the ID, Product_Name to the Name, etc.).

6. Validate the Data

• SAC will show a preview of the data you are importing. You can review it to ensure that the records align with the existing data.
• You can choose options such as Append (if you are adding new records) or Update (if you are modifying existing records).

7. Load the Data

• Once the mapping is done and you've validated the data, click Import.
• SAC will load the new data into the dimension.

8. Check for Errors

• If there are any errors during the import, SAC will provide a log. Check this log for details and correct any issues in the file (e.g., duplicate keys, missing required fields).

9. Save the Updated Model

• After the import is complete, don't forget to Save your model so that the dimension gets updated with the new records.

Best Practices:

• Check Data Types: Ensure that the data types in your file match the ones in the SAC dimension.
• Handle Duplicates: Make sure that if you're updating records, you have the correct unique identifiers (like Product_ID in the example) to prevent duplicates.
• Backup Existing Data: If necessary, make a backup of your existing data in case anything goes wrong during the import.

This process will update the dimension in SAC with the data from your file, appending new records or updating existing ones as necessary.
