Hi,
I'm a relatively new user to PowerBI and I really find this software amazing. However, I'm kind of stuck with one issue that I need help with.
I have a folder as a source (with about 3000 CSV files), and everything works fine.
Now the issue is that some of the CSV files contain a "unique ID" multiple times, and I would like to merge them into one row. However, mostly the value of almost all attributes contain the same thing, and I only need it to merge the values of a specific attribute. (preferably the ones without a blank value)
| UniqueID | Attr1 | Attr2 | Attr3 | Attr4 |
| Unique1 | AAA | 123 | 789 | |
| Unique2 | BBB | 123 | 789 | 111222333 |
| Unique3 | BBB | 123 | 987 | 222333444 |
| Unique1 | AAA | 123 | 789 | 444555666 |
| Unique4 | AAA | 123 | 456 | 555666777 |
| Unique2 | BBB | 123 | 789 | 111222333 |
| Unique1 | AAA | 123 | 789 | 444555666 |
So the idea is to have for Unique1 the Attr4 mergerd
However, for Unique2 the Attr4 is the same, so should should remain also the same.
So the desired result would be:
| UniqueID | Attr1 | Attr2 | Attr3 | Attr4 |
| Unique1 | AAA | 123 | 789 | 444555666 |
| Unique2 | BBB | 123 | 789 | 111222333 |
| Unique3 | BBB | 123 | 987 | 222333444 |
| Unique4 | AAA | 123 | 456 | 555666777 |
Is there any solution with PowerBI for my problem?
Kind regards.
