MDM Data Manager Assignments using Dates

Question

Hello.
I am trying to create some assignments that default to a certain date and my expressions are getting the error message when I execute them.
I am currently trying to create an Assignment for the Look-up table: Valid To (which belongs to the QT: Sales Data).
I want the Valid To Assignment to default at the date 12/31/2999 if the user did not already enter a value.
My expression looks like this:
IF (IS_NULL(Sales Data.Valid To), SYSTIME(0) = 12/31/2999)
I linked Sales Data for my 'Table Field'
Any Ideas?
Points awarded promptly for any help!
Thanks,
Nichole

Hi,
As per my knowledge, writing Assignments on Qualified Table field within the Main table is not possible for both Qualifier as well as Non-Qualifier Field. As if you want to write Assignment on Non-Qualifier fields only then you can do while selecting Qualified table as your Current Table not as Main table.
For Qualifier field too if you want to asign field using Main table is not Possible as you cant select Property Table Field as Valid to here you could only able to select all Main table fields and fields which is look up to this Qualified table and other Sub tables.
Don't confuse with other subtables.
Other assignments that i've made work with just the 'sales data' table field even though there is a lookup table within that Q.T.
That's why as you could get values for all other subtables in Assignment Expression as lookups tab if you remember like Reconcillation but here you could not find field who look up to your Qualified Table as well as Qualified table. there indirectly u r refering field to this lookup table and you get values here to assign but how could you assign value to Valid to field just think even if this is must requirement for you then you create one more subtable and look up this valid to field to this subtable or just create one more field  Valid to in maintable of type text.
So from my point of view this is only drawback that we could not Assign Value to Qualified table field. I hope it will help you in understanding. But writing Validations for Qualified Table fields is Possible but not Assignments. May be in MDM 7.1 its possible. This is my knowledge about Writing Expressions for Qualified Table Fields till now. 
Hope it will Help you,
