fill blank values with values in another column

Hi

 

I have done most of my calculations in power query editor.

 

As there are null values, I need to replace null values under Actual arrival date with values from Expected date of Arrival. How do I achieve this within power query editor.

 

As in below example, I need to fill rows 2 & 4 with the dates in Expected date of Arrival column

 

Actual arrival dateExpected date of Arrival
01-Aug-2001-Aug-20
 05-Aug-20
04-Aug-2004-Aug-20
 11-Aug-20

 

Thanks in advance for your support

 

Regards,

Muralidhar

Hi @murali5431 ,

 

Just realized that the you have made the incorrect formula is not case but Table.

 

 

= Table.ReplaceValue(#"Time to complete entry",each [Vessel_Actual_Arrival_Date__c], each if [Vessel_Actual_Arrival_Date__c] <> null then [Vessel_Actual_Arrival_Date__c] else [Vessel_Estimated_Arrival_Date__c],Replacer.Replacevalue,{"Vessel_Actual_Arrival_Date__c"})

Hi @murali5431 ,

 

Add a custom step and use the following code:

 

= Table.ReplaceValue(Source,each [Actual arrival date],each if [Actual arrival date] <> "" then [Actual arrival date] else [Expected date of arrival],Replacer.ReplaceValue,{"Actual arrival date"})

@MFelix .. Thanks for the response!

 

I am getting error when I added a new custom column as below

"Expression.Error: The name 'Case.ReplaceValue' wasn't recognized. Make sure it's spelled correctly."

 

I enetered as follows where "Case" is table name:

= Case.ReplaceValue(source,each [Vessel_Actual_Arrival_Date__c], each if [Vessel_Actual_Arrival_Date__c] <> null then [Vessel_Actual_Arrival_Date__c] else [Vessel_Estimated_Arrival_Date__c],Replacer.Replacevalue,{"Vessel_Actual_Arrival_Date__c"})

 

The previous step is "Time to complete entry", in case it helps.

Hi @murali5431 ,

 

First of all sorry for not refering that you must replace the Source by your previous step name so the values would be something similar to:

 

= Case.ReplaceValue(#"Time to complete entry",each [Vessel_Actual_Arrival_Date__c], each if [Vessel_Actual_Arrival_Date__c] <> null then [Vessel_Actual_Arrival_Date__c] else [Vessel_Estimated_Arrival_Date__c],Replacer.Replacevalue,{"Vessel_Actual_Arrival_Date__c"})

 

And this is not a new custom column you need to add a new custom step and then place this code on the formula bar, this will avoid creating new columns and deleting them.

 

Rigth click the last step on your query and then insert step after.

Hello @murali5431 

 

you can add a new column and make there a calculation like this

 

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMjDUdSxN1zUyUNJBYsfqRCspgERMkUUMTJDUmqCrNUTojgUA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [#"Actual arrival date" = _t, #"Expected date of Arrival" = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Actual arrival date", type date}, {"Expected date of Arrival", type date}}),
    #"Added Custom" = Table.AddColumn(#"Changed Type", "Actual arrival date new", each if [Actual arrival date]=null then [Expected date of Arrival] else [Actual arrival date]),
    #"Removed Columns" = Table.RemoveColumns(#"Added Custom",{"Actual arrival date"}),
    #"Renamed Columns" = Table.RenameColumns(#"Removed Columns",{{"Actual arrival date new", "Actual arrival date"}})
in
    #"Renamed Columns"

 

 

or you can use Table.TransformRows like this

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMjDUdSxN1zUyUNJBYsfqRCspgERMkUUMTJDUmqCrNUTojgUA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [#"Actual arrival date" = _t, #"Expected date of Arrival" = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Actual arrival date", type date}, {"Expected date of Arrival", type date}}),
    TransRow = Table.FromRecords(Table.TransformRows(#"Changed Type",(row)=> if row[Actual arrival date]= null then Record.TransformFields(row, {"Actual arrival date", each row[Expected date of Arrival]}) else row))
in
    TransRow

 

Copy paste this code to the advanced editor in a new blank query to see how the solution works.
