Actually I've a validation in a transaction based on a projectProperty. The validation is this:
%{11312} >= projectProperty("finifacturacion")
Where %{11312} is a selection date custom field and in the project I've defined the property: {finifacturacion=01/01/2015}.
I'd like to use the value of this property in the validation message. How can I do that? I've tried the following string but it doesn't work:
No es posible modificar los datos de facturación. La fecha tope para hacerlo era el + projectProperty("finifacturacion").
I have included parser function stringToDate(string_date, timezone). This function returns the numeric value for string containing a date-time value for a certain timezone. To implement your validation you should use Boolean validator with math, date-time or text-string terms with the following configuration:
Boolean expression used is: {11500} >= stringToDate(projectProperty("finifacturacion"), LOCAL)
Note that:
