Stepping through power query

[wynhodgkiss]

Hi all,

I am trying to isolate an issue with a power query I've inherited and the query in question has something like 1000 steps. Is there an easy way to step through the query without having to go step by step in power query or splitting the query?

At the moment I've got a line of "= Table.Group(#"Expanded Pack_Sort", {"Month"}, {{"Values", each List.Sum([SALES_VALUE]), type nullable number}} " that I'm shifting down the list of steps each time I get a correct outcome so I'll hit the issue eventually but it's painfully slow so just wondering if there's any more efficient way.

Thanks

Not really, there is no "error" in in the output it's just incorrect. I suspect that a filter has been applied wrongly or duplicates have been removed when they should not have been leading to incorrect values in the output, it's just slow trying to find the step in question particularly when 90% of the steps are called Custom1, Custom2 etc
