a!match(): tell a customer whether support is open

Medium

A help page shows the support desk's status. Days are numbered 1 (Monday) to 7 (Sunday) and hours 0 to 23:

  • Saturday or Sunday returns "Closed for the weekend"
  • a weekday from 9:00 until 17:00 returns "Open" (at 17:00 the desk has closed)
  • a weekday outside those hours returns "Closed"
  • a day number outside 1 to 7 returns "Invalid day"

A whenTrue condition can read other inputs as well as fv!value, and can be as rich as you need. Appian has no and or or operator. Use the and() and or() functions.

Appian Expression Tips

  • • Use ri!variableName for rule inputs
  • • Use a!localVariables(local!x: …, body) for locals
  • • Use a!forEach(items: …, expression: fv!item) to iterate
  • • Use where() / reject(fn!isnull, list) to filter
