Hi,
I couldn't find a solution to my problem and wanted to see if anyone could help. I have about 300k rows of data or else I'd do this in Excel. I am trying to look to see if ANY of the data in Group1 also shows in any of the other Group columns. Then I'd like to return "Yes" and the highest group for any of the rows it was matched in. So for below Group1 200 should return Yes in a column and also Group 3 in another column. Group1 100 should also return "Yes" and the highest group for the rows it was matched which is Group4. Group1 600 should say "No". Hope this makes sense.
| Group1 | Group2 | Group3 | Group4 | Group5 |
| 100 | 100 | | | |
| 200 | 100 | 200 | | |
| 400 | 400 | 400 | 400 | |
| 500 | 500 | 500 | 500 | 500 |
| 600 | | | | |
| 700 | 750 | 800 | 100 | |
| 1000 | | | | |
| 1200 | | | | |
| 1400 | 1000 | | | |
Thanks for taking a look.
