fill nulls with lookup power query

[fazza1991]

Hi,

I am looking to fill null values by a lookup using existing ID

eg

Name	Product
Test A	FM
Test A	FM
Test A	null
Test A	FM
Test A	null

as you can see from above test a has products but some come back blank due to nature of the database. i need it to lookup the existing name and fill the nulls.

i can't use fill up and down as not all will align correctly even if I sort by name etc.

Any help would be appreciated

HI @fazza1991,

I think you can group these records first and nested the 'fill down' function into these group functions. Then you can expand these records to get the filled-down records based on the group.

Solved: Fill down by group - Microsoft Power BI Community

If the above also doesn't help, please share some dummy data to help us clarify your scenario and test.
