Check Inputs (From User and Data Tables)

It is good practice to check whether the data are complete and decide for an appropriate action.

• If configuration data is missing and calculation does not make sense without them, use api.throwException().
• If missing or wrong values are allowed, you can solve it by using alerts (yellow, red, critical) or use api.abortCalculation(). 
  

  • You can create an additional field which shows to the user the alert reasons.

    Sample

    def priceType = "CostPlus"
    
    def price = null
    def reason = "Unknown error"
    
    def targetMargin = api.getElement("TargetMargin")
    
    if (targetMargin) {
      if (out.cost && out.VAT != null) {
          price = out.cost * targetMargin * (1 + out.VAT)
          reason = "OK"
      } else {
        reason = "No Average or Calculated cost price in PX Cost_RRP or VAT defined"
        api.redAlert(reason)
      }
    } else {
      reason = "No target margin defined"
      api.redAlert(reason)
    }
    
    api.local.reason = reason
    
    return price
