Requirement
I need to calculate the combined value of 10 specific pay components in SAP SuccessFactors Compensation. Right now, my rule breaks whenever one of those components is missing or null. The only way I’ve found to work around it is to write IF blocks for every possible combination (for example:
- “If Basic Pay and Housing are not null, then Total Salary = Basic Pay + Housing”
- “If Basic Pay and Bonus are not null, then Total Salary = Basic Pay + Bonus”
- …and so on for dozens of permutations),
which is unmanageable.
What I Want
A simple Business Rule pattern that:
- Defines my 10 pay component fields once,
- Automatically treats any missing/null component as zero,
- Sums only the non-null components,
- Never fails when a component is absent,
- Doesn’t require writing dozens of IF-combinations or using pay-component groups.
Example of Desired Behavior
- Employee A has Basic Pay = 5,000, Housing Allowance = 2,000, all other components null → Total = 7,000
- Employee B has Bonus = 1,500, Travel Allowance = 800, all others null → Total = 2,300
- Employee C has none of the 10 components → Total = 0
How can I implement this “sum only non-null fields” logic in a single, maintainable Business Rule? What best practices or built-in functions can I leverage so I don’t have to hard-code every combination manually?
