Hello everyone,
I’m trying to join three datatable into one datatable but I encountered this error:
I’m aware that this error appear only when the specified column name does not exist in the table that i’m trying to filter. I have double check the column names to make sure that there are not typos but everything seems to be fine.
Here are my table i’m trying to join:
DT1
DT2
DT3
Here is my join operation down below. As you can see the column name down below match with the table above.
I couldn’t figure out why it still throw me that error even though everything seem to match. Can anybody help me with this? I would greatly appreciate the help.

Thank you and regards,
