So the source owners can piece that together with the delimiter, but can't create an "Anaplan" code for those pieces and do an inner join on those tables? Ok, if that is the case, then you will have to break "best practices" and use Combination of Properties with your code being the display name which will make this much more difficult especially when importing the transactional data. Again, I would go back to the owners of the data to see if they can give you the codes instead of the text. Also, are you sure you need all 10 members of the code to make it unique? And just to make sure, you don't have Time Period as part of the code, correct?
