@ArunManickam Thank you so much for your suggestion! However, it appears that "Last transaction" line item in Module "Transaction data- By dimension" is empty. How did you get them in your test model? Thanks!
Just wanted to pass this along, but the period should not be part of the code. In this instance, if I am reading it correctly, the code or list member should only be the transaction number (1062155501, 1062155531, 1062155503, etc.). Take a look at this article which shows why having date or period in the code is not good for performance:
Yes, the concatenation of those combination without date is only on the List once by using 1st occurrence. The reason for including date in the "unique" ID is to capture all transactions. I wish that we have better clean data to deal with. Thanks!
