I’ve loaded a .txt file into PBI and am getting duplicates in what should be a column of unique values. These don’t appear in the source and when I load the same data into Tableau this doesn’t happen.
The data has 7022 rows but PBI only recognises 6989 unique values in the id column. I’ve copied one such duplication below. As you can see, the id with the suffix 96 is duplicated and the second takes the place of the one which would have had the suffix 100.
id | Canvas_id |
70360000000000093 | 93 |
70360000000000094 | 94 |
70360000000000095 | 95 |
70360000000000096 | 96 |
70360000000000096 | 100 |
70360000000000097 | 97 |
70360000000000098 | 98 |
70360000000000099 | 99 |
70360000000000101 | 101 |
70360000000000102 | 102 |
Does anyone know what might be happening here?
