Calculating time between steps

Hi,

 

I have been stuck on this now for a little and cannot seem to figure it out.

 

I have the following table:

 

item nostep astep bstep cstep d
item 111/20/2016 11/29/2016 
item 2 11/15/2016  
item 3    
item 4    
item 511/1/201611/22/201611/28/2016 
item 611/2/2016  11/29/2016
item 7    
item 8 11/29/2016  

 

 

What I'm trying to do is figure out how long the time difference is between steps. Not all steps are used for each item. My output could be something like this (but if there are better ways to output I don't mind):

 

item nostep astep bstep cstep d
item 1  9 
item 2    
item 3    
item 4 216 
item 5   27
item 6    
item 7    
item 8    

So for example, I could say on item 1 step C took 9 days since the last copmpleted step, which is enough detail. I'm struggling trying to find a solution, on how to arrange this in Power BI. Initially I've been trying along the lines of transpose and fill down, but this has not been working for me.

 

Thank you in advance for your help!

Check this out:

 

    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WyixJzVUwVNJRMjLQNzTUNzIwNANyQHxLZH6sDlSpEUTW0BRVNUKBMVQATdgEu7ApkGdgiGSWkREyxwKrG0A8AyM0B6C4GK7UHLu1Ftj8CFIQCwA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type text) meta [Serialized.Text = true]) in type table [#"item no" = _t, #"step a" = _t, #"step b" = _t, #"step c" = _t, #"step d" = _t]),
    #"Unpivoted Other Columns" = Table.UnpivotOtherColumns(Source, {"item no"}, "Attribute", "Value"),
    #"Filtered Rows" = Table.SelectRows(#"Unpivoted Other Columns", each ([Value] <> "")),
    #"Changed Type" = Table.TransformColumnTypes(#"Filtered Rows",{{"Value", type date}}),
    AddIndex = Table.AddIndexColumn(#"Changed Type", "Index", 0, 1),
    #"Added Custom" = Table.AddColumn(AddIndex, "Duration", each if [Index]>0 and [item no]=AddIndex[item no]{[Index]-1} then Number.From([Value])-Number.From(AddIndex[Value]{[Index]-1}) else "" ),
    #"Removed Columns" = Table.RemoveColumns(#"Added Custom",{"Index", "Value"}),
    #"Pivoted Column" = Table.Pivot(#"Removed Columns", List.Distinct(#"Removed Columns"[Attribute]), "Attribute", "Duration")
in
    #"Pivoted Column"

 

If you also need the empty item numbers, just let me know.

You are awesome - that works perfectly! I've just started learnign DAX / Power Query so walking through your steps really helps me unsderstand the logic.

Thanks a lot!
