I had perfectly working custom column, which worked fine when created in "Data" view of Power BI. No errors.
When I deleted column and tried to create again in "Edit Query" view (Edit Query->Add Column->Custom Column->Custom Column Formula), I'm getting error. Why exactly same DAX formula is not working?
MachineId =
CALCULATE (
FIRSTNONBLANK ( Machine[MachineId], 1 ),
FILTER ( ALL ( Machine ), Machine[MaintenanceId] = MachineSelectedForUnion[Code] )
)
Solved! Go to Solution.
Hi @Anonymous
You can't use DAX within Power Query - Power Query uses the M language.

Hi,
check the relationship, it was posible to had breaken when you deleted the column.
Hope it helps,
