Conditional Filter Power Query - Same Column

[sovereignauto]

Afternoon,

Im looking to filter a column [updated_date] (date/time) for the last 2 months or the last 6 months if [type]="ABC"

So all records for the last 6 months where type = "ABC" 

and every other record for the last 2 months 

thank you!

Hi, If your Source is SQL then You can use "Query Folding" in order to achieve this.
Create a parameter (Parameter_Name) and in the where clause set the condition as follows:
Select * from table_name where the Field_name = Parameter_name

Hi, @sovereignauto 

According to your description, I can clearly understand your requirement, you can try my steps in the Power query:

This is the test data I created:

1. Create a custom column and enter it like this:

if Date.IsInPreviousNMonths([Date],2) or  Date.IsInCurrentMonth([Date])

then

1

else

if Date.IsInPreviousNMonths([Date],6) and [Type]="ABC"

then 1 else 0

2. Filter the table like this:

3. Remove the custom column:

4. Then click on the “Close and apply” to import the filtered table into the Power BI

And you can get what you want.

You can download my test pbix file below

If this result is not what you want, you can post some sample data(without sensitive data) and your expected result.

So i added the Column as you and @amitchandak  suggested. 

i Guess my issue is that it still syncs over 10m records so guess i need to filter before load into powerbi is that right?

@sovereignauto , Try a new column like and then you can filter 

if Date.IsInPreviousNMonths([Date]) && [type]="ABC" then 1 else 0

if need use Date.IsInCurrentMonth

if (Date.IsInPreviousNMonths([Date]) ||   Date.IsInCurrentMonth([Date]) ) && [type]="ABC" then 1 else 0
