Replace value in Power Query based on condition

Dear all,

 

I have a table ("POs") with a list of POs which have some fields that in very specifics moments have wrong entry inputs. For example in the following table the PO "1006" should have the Category "C" instead of the Category "D":

 

PO Category Amount
1001 A 1050
1002 A 1327
1003 B 1276
1004 B 1383
1005 C 1967
1006 D 1288
1007 E 1707
1008 F 1233

 

I tried to use the ReplaceValue option in Power Query but it replaces all the the Categories "D" of all the "POs". I just want to replace the category of the PO "1006".

Thanks

HI @JoaoMS,

You can use replace value function with custom expression to add conditions to replace value steps:

    #"Replaced Value" = Table.ReplaceValue(#"Changed Type",each [Category],each if [PO]=1006 and [Category]="D" then "C" else [Category],Replacer.ReplaceText,{"Category"})

Dear community, I've got also issue with the creation of the "replace" code.

I need to replace value based on multiple condition.

I've attached and extract of the data that I want to manage.

They are the conditions that I would like to apply :

If [Billing code - description] = "--Unknown billing code--" AND [User - name] = "svMedIS_App Compte de service RadOffice" AND [Location] = "Rennaz" then [Billing code] = "A" else "No change"

If [Billing code - description] = --Unknown billing code-- AND [User - name] = svSIMop Compte de service Logimen AND [Location] = Rennaz then [Billing code] = "B" else "No change"

If [Billing code - description] = --Unknown billing code-- AND [User - name] = svSIMop Compte de service Logimen AND [Location] = Providence then [Billing code] = "C" else "No change"

 

here the dataset I used for my test 

Thanks for your reply and help

Thank you, this is what I was looking for without creating a new column. I just made a small change "each if [PO]=1006 then "C" else [Category]", considering that there is just one PO named "1006" Regards

Try this way : 

 

Step1 combine column " PO" and " Category" , 

Step2 replace"1006D" into "1006C" 

Step3 Split the combined column to " PO" and " Category"

@JoaoMS , Something like this

if [PO] = "1006" then Text.Replace([Category], "C", "D") else [Category]

 

This is new column script
