Calculation with different data types

[WJ876400]

Hi

I have the below table, I have put what data type they are above each header. What I want to achieve is the outcome column, the outcomes are below. I am struggling with the different date formats

If Last Review is blank = To be scheduled

If Next Review - Last Review is <=30 = To be scheduled

If Next review - Last Review is >30 then use the date in next review

DATE/TIME (dd/MM/yyyy)	TEXT
LAST REVIEW	NEXT REVIEW	Outcome
23/07/2019	26/11/2019	26/11/2019
	To be scheduled	To be scheduled
	To be scheduled	To be scheduled
24/09/2019	To be scheduled	To be scheduled
24/09/2019	25/09/2019	To be scheduled
17/06/2019	24/06/2019	To be scheduled
17/06/2019	10/10/2019	10/10/2019
01/08/2019	02/12/2019	02/12/2019

thanks

Hi,

This M code works

let
    Source = Excel.CurrentWorkbook(){[Name="Table1"]}[Content],
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"LAST REVIEW", type datetime}, {"NEXT REVIEW", type any}}),
    #"Added Custom" = Table.AddColumn(#"Changed Type", "Custom", each if [NEXT REVIEW]="To be scheduled" then "To be scheduled" else if Number.From([NEXT REVIEW]) - Number.From([LAST REVIEW])<30 then "To be scheduled" else [NEXT REVIEW])
in
    #"Added Custom"

Hope this helps.

hi, @WJ876400 

For your case, just try this formula to create a column

Column = 
IF (
    'Table'[LAST REVIEW] = BLANK (),
    "To be scheduled",
    IF (
        'Table'[NEXT REVIEW] = "To be scheduled",
        "To be scheduled",
        IF (
            DATEDIFF ( 'Table'[LAST REVIEW], DATEVALUE ( 'Table'[NEXT REVIEW] ), DAY ) > 30,
            FORMAT ( 'Table'[NEXT REVIEW], "dd/mm/yyyy" ),
            "To be scheduled"
        )
    )
)

Result:

here is sample pbix file, please try it.

Hi @v-lili6-msft 

thanks for the help. I have added in a column and put in the formula but it doesn't seem to work for certain fields. It is not putting to be scheduled where the last review is blank and the next review is to be scheduled. It is also not using the next review date when the next review is 30 days greater than the last review. The column is going in the values of the matrix table because of the way it is contsructed if that is causing an issue?

thanks

The column is going in the values of the matrix table because of the way it is contsructed if that is causing an issue

Column in matrix value will be aggregated, this should be the reason for it.

And this formula is used for a calculated column, so it will work in data table, You may adjust the formula as a measure.

If you still have problem, please share your sample pbix file for us have a test.
