Issues with request Parameter with new obsolete definition

Why don't you just set (Max. days valid = 7) on the Service Item?
AccProduct.MaxValidDays

 i am using the request property with new style definition. How do i declare the column values of table (AccProduct.MaxValidDays) in my validation script? I know to do this with the obsolete definition.

Ex. you give the parameter name the same name as the colomn ex: ValidUntil
Valuation script : Value = Provider.GetValue(Of Date)("ValidFrom").AddDays(7)
Validation script: If Provider.GetValue(Of Date)("ValidUntil") > Provider.GetValue(Of Date)("ValidFrom").AddDays(7) Then
   Throw New ViException("Some text...", ExceptionRelevance.EndUser)
End If

Thanks for your response! However, This is still not working. Maybe there is some problem with the 'valid from' valuation script (below) i am using here.

the requirement is to enforce that the "Valid From" date is always set to today's date (request date) even if the user selects a different date. can you help me with the valuation script & validation script here? Maybe i can try the valid Until later once this is fixed.

I thought it would work, but I can also confirm that it doesn't.
It does something when set to Parameter type = 'User prompt' but does nothing when set to = 'Fix'.
Don't know if this is a bug or this approach is just a glitch.

Don't have time to investigate right now
As a work-around maybe you could do something with the value temple of ShoppingCartItem.ValidFrom
Just rough example 

If String.Equals("56b0630e-05ca-4227-a2d7-5de6d916dafa",
        Provider.GetValue(Of String)("UID_AccProduct"),
        StringComparison.Ordinal) Then
        
    Value = DateTime.Today.AddTicks(1)
End If

Thanks, i cannot use the column templates because i need few customized parameters that returns all the userid the logged in user has , i couldnot achieve it with obsolete definition hence used the non-obsolete one which has more options to customize.
