I am trying to create validation rule, when closing the case if product type and component and subcomponent is empty to fill the values.

ISBLANK(Account.Name) ,
ISPICKVAL( Status, "Closed"),
RecordType.Name = "Support Case")

I have given defalut value as None in picklist fields.

This doesnt detect the null value for picklist values, not able to figure out why. Can some one please help what I am doing wrong.

  • How are you sure the picklist are the issues? Have you tried removing them and testing to see if it triggered? Jan 16, 2020 at 1:04

This might be due to the way ISBLANK and ISNULL differs by definition ISBLANK determines if an expression has a value then returns TRUE if it does not contains a value, then this function returns FALSE. ISNULL determines if an expression is null (blank) then returns TRUE if it is. If the expression contains a value, then this function returns FALSE. Did you try ISNULL in validation rule?

  • ISBLANK has the same functionality as ISNULL, but with the added supported for text fields plus it's recommended per the docs for new formulas Jan 16, 2020 at 11:32
