change column value based on condition

[powerbricco]

Dear All,

I have a table that looks like this:

Code	Value1	Value2
0001	100	200
0002	50	500
0003	10	20
0004	150	300

I'd like a condition in Power Query for which:

- if row meets Code = 0003, then Value1 and Value2 must be divided for 12.

I do not want to generate other columns, just want to substitute values in Value1 and Value2.

Desired result:

Code	Value1	Value2
0001	100	200
0002	50	500
0003	0,833333	1,66666
0004	150	300

Thank you a lot

@powerbricco try this, change column name as per your table:

Table.ReplaceValue(#"Changed Type",each [Value],each if [Code] = 1 or [Code] = 2 or [Code] = 3 then Date.Month([Date]) else [Value],Replacer.ReplaceValue,{"Value"})

@powerbricco here is the output for [value1] after replace is applied.

@powerbricco add a replace value step and change it as shown below, do it for both value 1 and value 2

= Table.ReplaceValue(#"Changed Type",each [Value1],each if [Code] = 3 then [Value1] / 12 else [Value1], Replacer.ReplaceValue,{"Value1"})

Dear @parry2k , it does work perfectly!

May I ask you another advice?
Let's say I have a date column. Every time rows meet codes 001, 002, 003 and 0004, each Value1 should be replaced with month in date column. How can I write that?

Thank you a lot..
