Merging the differences between 2 tables

I've looked around and I'm not sure if this is possible using Power Query.

 

I have multiple excel files, all containing the exact same table. Same columns, same rows etc. Except the rows are filled in by different teams using their own copy of the file. They want them all merged into one master file.

 

I've only been able to append them to eachother which results in duplicated IDs.

 

Example with dummy data:

 

Table 1:

IDStatusHours Taken

123

  
456Complete4
789Complete7.65

 

Table 2:

IDStatusHours Taken

123

Complete6.43
456  
789  

 

Output Table:

IDStatusHours Taken

123

Complete6.43
456Complete4
789Complete7.65

Hello @SClarke501 ,

 

You could add a column for each table to specify the team.

How exactly would that produce my desired output?

 

The team is largely irrelevant. It just needs to merge into one master document where all rows are filed in. Your solution would give me the same duplicated rows but with the team next to it, which doesn't allow me to eliminate rows?

Hi @SClarke501 ,

 

You can use append queries and filter on column values.

An additional step can be taken to remove duplicate records if necessary.

let
    Source = Table.Combine({Table1, Table2}),
    #"Filtered Rows" = Table.SelectRows(Source, each ([Status] = "Complete")),
    #"Removed Duplicates" = Table.Distinct(#"Filtered Rows")
in
    #"Removed Duplicates"

The problem is there will be blank rows and I don't want to get rid of them. Filtering them out after the fact will only show the ones that have been filled in by someone, but this is for a master record that contains everything.
