This post covers following high level steps for adding new custom measures/metrics to out of the box (seeded) HCM subject areas.

A. Identify custom measures

B. Construct the formula

C. Extend Semantic Model

D. Publish, test and merge Semantic Model

E. Version and Promote to production
 

1. Identify custom measures that are frequently used by your business users. Let’s consider an example, “APAC Headcount”.

2. Construct, validate and test your custom formulae in OAC projects:
 FILTER("HCM - Workforce Core"."Facts - Workforce Headcount"."Headcount" USING "HCM - Workforce Core"."Location"."Country" IN ('India',     'Philippines', 'China', 'Singapore'))

Few more examples:
Twelve Month Rolling Attrition:
(((PERIODROLLING("Core"."Fact - Assignment Event"."Voluntary Termination Headcount"+"Core"."Fact - Assignment Event"."Involuntary Termination Headcount", -13,-1)))/((((PERIODROLLING("Core"."Fact - Assignment"."Headcount", -13, -13))+(PERIODROLLING("Core"."Fact - Assignment"."Headcount", -1, -1)))/2)))

EMEA Employee FTE:
FILTER("Core"."Fact - Assignment"."Employee FTE" USING "Core"."Dim - Worker Location"."Country" IN ('UK', 'France', 'Germany'))

3. Semantic Model Extensions:

    a. Create a custom branch
        In Oracle Fusion Analytics Warehouse, open the Application Navigation menu, click Console, and then click Semantic Model Extensions. On the Semantic Model Extensions page, click Create and then click Create Branch to create a branch as an empty container. In Create a Branch, enter a name for your branch, for example: Custom Metrics.
        

    b. Add a Step
        On the branch page, click Add Step -> Add Derived Columns
        

        Add details for the step, choose HCM - Workforce Core for the target subject area and Facts - Workforce Headcount for the Folder.
        


        Create columns for custom measures:
        

        
       
You can add other columns here - click on Create Column

When done adding all columns - Click on Finish.
        

    c. Merge, Version, and Promote
        On the Semantic Model Extensions page, under Other Branches, hover over a branch to view the Actions menu. Click Merge with Main
        

        Create a Version and include the merged branch
        
Custom branch is merged with Main - and versioned, it's now ready for Promotion (migration) to Production instance.
        

Verify the custom measures show up in HCM - Workforce Core subject area -> Facts - Workforce 

        



d. Promote the changes to Production Environment
    In Oracle Fusion Analytics Warehouse, open the Application Navigation menu, click Console, and then click Promote Objects. You see the Promote Objects page.
    

On the Promote Objects page, select the target environment to which you want to publish your customizations. Select the Semantic Model Extensions check box and the saved/latest version of the main branch, in our case, it is - Custom_Measures_V1

  • HI Ravi,

    I have followed the above steps and merge the custom branch changes to main as per following statement but

    "On the Semantic Model Extensions page, under Other Branches, hover over a branch to view the Actions menu. Click Merge with Main"

    but I am still not able to see the custom metrics in the workforce core subject area. I have published the custom changes as well. Can you please let me know what step I am missing here. I was not able to see any version option in FAW instance. Instance is on 21.R2.P5.

    Regards,

    Ankur
