Hello all,
I have issue with removing certain part of string value in my column.
Example:
Table "Document"

| 61-2300-B-PID-2350-01-07812 | Project Working Copy |
| 61-2300-B-PID-2350-01-07917D | Project Working Copy |
| 61-2300-B-PID-2350-01-07917 | Project Working Copy |
| 61-2300-B-PID-2350-01-14398 | Project Working Copy |
| 61-2300-B-PID-2350-01-00209 | Project Working Copy |
| 61-2300-B-PID-2350-01-07812-21 | Project Working Copy |

Thank you!
Hi @Anonymous one possible solution could be to create new column in Power query using M function Text.Start
(I recognize pattern from your picture: first 21 character should retrive):
New column Document cut code is
= Table.AddColumn(#"Promoted Headers", "Document cut", each Text.Start([DocumentNumber],21))
I hope this help
