    How do you create a field (& populate it) using a field from a crosstable?

      I apologize for the vague header...

       

      I am trying to create a 'Unique Key' table which will be made up of 2 fields. The two fields I am joining are [Negotiator] and [Full Date] (full date is Month and Year spanning May 2015 to December 2017). In short, I want to create a table with every permutation of name and date. I need the unique key because the relationship between name and date becomes many-to-many as I pull in more data points in - example of what I need:

       

          ' John May 2015

           John June 2015...

           ... John December 2017

      ....

           Mike May 2015

           Mike June 2015...

          ... Mike December 2017

      ....

           Jane May 2015

           Jane June 2015...

          .... Jane December 2017 '

       

       

      I tried keeping it simple and just combine the two, something like: Negotiator & [Full Date] as [Unique Key]

      ... but quickly realized QV cannot recognize the field [Negotiator] as a relatable field; something to do with it being created in the crosstable.

       

      Below is an outline of my query:

       

      CrossTable([Negotiator], Data_QA)
      LOAD Date as [Full Date],
      [John Doe],
      [Mike Doe],
      [Jane Doe]

      - (there are about 40 names) -


       


       

      Hope this is enough information to understand the issue. Any guidance / suggestions on how to create this joined unique key field?
