Parameters

Field selection

  • source — Field whose values this operation reads. Use a single field name, a comma-separated list of plain field paths (cash_flow_type, currency) from the multi-select UI, or a regex via Pattern mode. Omit to apply to all fields on the row.
  • target — Optional output field. When omitted, the source field is updated in place. Hidden when more than one named source field is selected.
