Replace null values in date column

Hi I have a column with promised delivery dates. The Excel sheet I'm importing this data from has some blank values for this column which are coming in as null values which is messing up my calculation for delay in delivery (promised minus actual delivery date). I tried to replace the null values but they can only be replaced with date values which again will throw off my calculation for delay in delivery. Is there a way around this? I can't change the data type of the date column into text or anything else as I need to be able to perform calculations.

Hi,  @fayanan 

It is unnecessay to replace the blank value in 'proposed delivery dates'.

You just need to consider using t "if" function to discuss the situation.


delay in delivery =
IF (
    ISBLANK ( [proposed delivery dates] ),
    BLANK (),
    [proposed delivery dates] - [actual delivery date]

you can fill up or fill down in the PQ to remove null


you can also replace null with specific value


you can also use min or max to get the data
