Define Column Order using SELECTCOLUMNS
I'm using SELECTCOLUMNS to project a subset of fields from my data model onto an Excel worksheet. The example uses the expression below to force the columns to appear in the order I want them displayed.
EVALUATE
SELECTCOLUMNS (
'GES BB Invoice Data',
"ESS Key", 'GES BB Invoice Data'[ESS_KEY],
"Inv #", 'GES BB Invoice Data'[Inv Num],
"Source", 'GES BB Invoice Data'[Source],
"Inv Amt Claimed", 'GES BB Invoice Data'[Inv Claimed Amt],
"Unclaimed Amt", 'GES BB Invoice Data'[UnclaimedDeniedAmt],
"Reason", 'GES BB Invoice Data'[Reason],
"Inv Status", 'GES BB Invoice Data'[Inv Status]
)However, the result appears in a completely random order.
Can anyone explain why? Or how to get the results I need?
Thanks,
Rich P
Hi Rich_P ,
As this case, the ORDER BY clause is part of the EVALUATE statement and the drillthrough expression just accepts a table expression. One possible work around would be to wrap your SELECTCOLUMNS in a TOPN. You could then either set a reasonable limit on the drillthrough to stop people from trying to extract too much data or you could just put a huge number for the "N" amount (eg. 2 billion) so that it just does sorting, but does not realistically limit the rows.

Hi Rich_P ,
Does that make sense? If so, kindly mark my answer as the solution to close the case please. Thanks in advance.
This question is about column order but the accepted answer is about data (row) order. How can the answer be 'correct'?
