Problem with changing the type of date needed for incremental refresh

I’m asking for your help. I know that I can do incremental refresh in premium version but I came to the point that first I need to convert the date format „YYYMMDD” into power query on datetime with function (x as datetime) => Date.Year(x)*10000 + Date.Month(x)*100 + Date.Day(x).

Unfortunately I can’t handle it. Please help me how to do it. I attach an pbx file with a sample of csv data.

Hi @Harris,

As I understand it you need to convert the DimDate_ID into a value of datetime type.
First extracted the date

Then converted the date to type datetime now there is no time value so each record has time 00:00:00

Also added the Parameters for RangeStart and RangeEnd and filterd your data table.

Here’s the file. I hope this was helpful.
