Conditional Table.ReplaceValue (if to define it replace will be applied or not)

[rafaelsmoreno]

Hi

I have query with 3 columns: InvoiceNumber, InvoiceType and InvoiceAmount. There are 40K+ records, and half a dozen of them have the wrong InvoiceType (need to change com "Service" to "Product"

So, I put up this code:

replaceType =
if "InvNumber" = "30881" and "InvType" = "Service" then Table.ReplaceValue(replaceCarga, "Service", "Product", Replacer.ReplaceText, {"InvType"})
else if "InvNumber" = "30769" and "InvType" = "Service" then Table.ReplaceValue(PreviousStep, "Service", "Product", Replacer.ReplaceText, {"InvType"})
else if "InvNumber" = "30770" and "InvType" = "Service" then Table.ReplaceValue(replaceCarga, "Service", "Product", Replacer.ReplaceText, {"InvType"})
else if "InvNumber" = "30771" and "InvType" = "Service" then Table.ReplaceValue(replaceCarga, "Service", "Product", Replacer.ReplaceText, {"InvType"})
else if "InvNumber" = "30772" and "InvType" = "Service" then Table.ReplaceValue(replaceCarga, "Service", "Product", Replacer.ReplaceText, {"InvType"})
else if "InvNumber" = "30791" and "InvType" = "Service" then Table.ReplaceValue(replaceCarga, "Service", "Product", Replacer.ReplaceText, {"InvType"})
else if "InvNumber" = "31261" and "InvType" = "Service" then Table.ReplaceValue(replaceCarga, "Service", "Product", Replacer.ReplaceText, {"InvType"})
else if "InvNumber" = "31262" and "InvType" = "Service" then Table.ReplaceValue(replaceCarga, "Service", "Product", Replacer.ReplaceText, {"InvType"})
else if "InvNumber" = "31336" and "InvType" = "Service" then Table.ReplaceValue(replaceCarga, "Service", "Product", Replacer.ReplaceText, {"InvType"})
else if "InvNumber" = "31337" and "InvType" = "Service" then Table.ReplaceValue(replaceCarga, "Service", "Product", Replacer.ReplaceText, {"InvType"})
else "InvType"="InvType"
in
replaceType

The thing is it is not working at all. I don't know how to instruct a "do nothing" in the last else. Any ideas?

@rafaelsmoreno，

Is this query a custom function or others? Which error occurs when you implement it?

Hi

It's the standard replace value function from power query. The point is that I cannot make it work with if statements inside it.

I believe you can also create a quick table of replacements and then merge the 2 fields of both tables

InvNumber	InvType	Correct Replacement
30881	Service	Product
30769	Service	Product
30770	Service	Product

Zubair, that seems to be the easier way to go, thanks for that. I'll use it, because in the end of the day, it solves the problem. 

In the meantime I really wanted to improve my "IF" skills. This "do nothing' at the end of the if then else statement is really troublesome.  Let's see if somebody come up with an insight on that. 

Best regards,
