Convert Multiple rows with duplicate into unique single row

Hi,

 

I have several rows of data in my dataset. Each row duplicates since I have to consider two types of Action "A" & "L". This causes the row volume to double, as below:

 

CodeNameActionID
ABCPeterAD100
ABCPeterLD200
ABDCharlieAD150
ABDCharlieLD250
ABEJackAD110
ABEJackLD220

 

Is there a way I can bring the data into single rows using power query, as in table below?

 

CodeNameActionIDAction1ID1
ABCPeterAD100LD200
ABDCharlieAD150LD250
ABEJackAD110LD220

 

Thanks in advance!

First pivot the Action and ID columns.  Then unpivot each separately.

in
    #"Unpivoted Only Selected Columns1"
