List view error “Filter Value is not in a supported date format”

Question

I've column "Name = Order Status","Type = Calculated" & Data Type = "Date and Time". I've given this Condition in the formula:- =IF(NOT([PO Date]=0),"ORDERED","NOT ORDERED"). I'm trying to create view for this column but its getting error while create the view "Filter Value is not in a supported date format".

Same error I'm getting for column "Name = Status","Type = Calculated" & Data Type = "Number". I've given this Condition in the formula:- =IF([PO Date]="","",IF(NOT([Balance Qty]=0),"OPEN","CLOSED"))

Please advice.

Answer 1

Check if column is empty with ISBLANK() function:

=IF(ISBLANK([PO Date]),"NOT ORDERED","ORDERED")

I recommend you test your formula in Excel first, because SharePoint uses Excel engine for calculated columns and validation rules. And here nice article about formulas in SharePoint:
