Hi all,
I have a client masterfile table included in my data model. The table is linked in DirectQuery mode from a SQL Server. In the table query I have added some lines to mock up the data but when I try to replace values in a column based on condition I fail and get the following message:
This is the step I need to do:
= Table.ReplaceValue(#"Filtered Rows", each [Group], each if [Group] = "” then [Company] else [Group], Replacer.ReplaceValue, {"Group"})
Practically I need to have all cells in column Group filled either with the preexisting value or with the value present in the Company column (both text fields)
I can't believe this is not possible in DirectQuery mode. What am I doing wrong?
Thanks,
C.
Hi there, thanks for your reply.
I did actually try the first method above and it did not work. After adding the new column I couldn’t populate it conditionally and got the same message. I will try the second solution (If I can find the way). At the end if nothing works I will accept the import mode but we are talking about a very large table to be possibly used in several reports and would be a real waste of space.
Many thanks indeed; I will let you know how it goes.
Regards,
C.
@Anonymous,
One approach would be to add a custom column in Power Query with the "if" statement, and then remove the original column Group. You could also use custom SQL with a CASE statement. With custom SQL, you'll need to put all transformations in the SQL (no M transformations).
