How it runs
Trigger: Manually, when you click “Execute workflow”.
- Input: Inflation & Returns (Edit Fields (Set)): sets or maps fields
- Validate Input (If): checks a condition and branches into true / false
- Compute Real Returns (Code): runs custom JavaScript code
- Check Invalid Inputs (Edit Fields (Set)): sets 1 field: Error
- Split Commodities (Split Out): splits a list into separate items
- Check Better Than Savings (If): checks a condition and branches into true / false
- Label as GOOD (Edit Fields (Set)): sets 1 field: category
- Label as BAD (Edit Fields (Set)): sets 1 field: category
- Merge: merges the data from its input branches
- Aggregate: combines items into one
…plus 3 more steps. See the full node list below.
