Using Miscellaneous Fast Formula Functions in BI Publisher
GET_VALUE_SET streamlines Oracle BI Publisher data models by tapping into table-validated value sets for secure, dynamic lookups, eliminating redundant SQL in reports.
Core Function Mechanics
GET_VALUE_SET(value_set_code, bind_string) pulls the first row from a table value set. The bind string supplies parameters like |=P_PERSON_ID='12345'|P_DATE='2025-12-31', which filter the value set’s WHERE clause for targeted results such as HCM balances or employee details.
Data Model Integration
Embed it in BI Publisher derived columns or expressions:
Build binds dynamically:
'|=P_EMPLOYEE_ID=' || :p_emp_id || '|P_PERIOD=' || :p_period.Invoke
GET_VALUE_SET('MY_VALUE_SET', bind_str)for runtime resolution.Output becomes straightforward fields for templates, syncing reports with centralized value set rules.
SQL Testing Example
Debug or directly use pay_ff_functions.gvs in a BI Publisher data model SQL query from DUAL:
SELECT pay_ff_functions.gvs('XX_GET_PERSON_NUM','|=PERSON_ID=900000088911218') AS person_number
FROM dual;
This mirrors fast formula behavior, testing value sets like assignment lookups before report deployment.
Key Tips
Limit value sets to one row per bind to capture the correct data.
Null-proof with
NVL(GET_VALUE_SET(...), 'DEFAULT').Switch to SQL views for multi-row needs; pair with fast formulas for HCM contexts.
