Automatic Computed Value of Properties through VBScript

Had similar case where I needed to calculate amount including VAT. You can use the script with a few adjustments.

'Script for calculating invoice amount + VAT, automatic value
Option Explicit
Dim iPDAmount : iPDAmount = Vault.PropertyDefOperations.GetPropertyDefIDByAlias("PD.Amount")
Dim iVAT : iVAT = 25 'percentage of VAT
Dim szAmount : szAmount = PropertyValues.SearchForProperty(iPDAmount).TypedValue.DisplayValue
'err.raise mfscriptcancel, szAmount & "  " & szAmount * ("1," & iVAT)
if not szAmount = "" then
	Output = szAmount * ("1," & iVAT)
end if

Hi, you can also do that without coding with Extension Kit Auto properties module.

 

Kind regards,

Hi Katarina,

Thanks for this but as of right now we do not have that module, But we are planning to have it so I will make this a reference in the future.
