DAX Formula for Checking if First Rev Date is Not Blank

Formula

To create a DAX formula that checks if the "First Rev Date" is not blank, you can use the following code:

FirstRevDateCheck = IF(NOT(ISBLANK([First Rev Date])), "Date Exists", "Date is Blank")

Explanation

Components of the Formula

• IF Function: This function evaluates a condition and returns one value if the condition is TRUE and another value if it is FALSE.
• ISBLANK Function: This function checks whether a specified value is blank. It returns TRUE if the value is blank and FALSE otherwise.
• NOT Function: This negates the result of the ISBLANK function, meaning if a date exists (is not blank), it will return TRUE.

Logic Flow

1. The formula first checks if the value of [First Rev Date] is not blank using ISBLANK.
2. If the value is not blank, it returns "Date Exists"; otherwise, it returns "Date is Blank".

Practical Example

Assume you have a table named Sales with a column First Rev Date. You can create a new calculated column using this DAX formula to categorize the entries based on whether the First Rev Date is available.

With the formula applied, your resulting table may look as follows:

In this example:

• For Sales ID 1 and 3, the First Rev Date is not blank, leading to "Date Exists."
• For Sales ID 2, the First Rev Date is blank, leading to "Date is Blank."

Conclusion

This DAX formula effectively allows you to determine the presence of a value in the First Rev Date column while providing meaningful feedback on the results. By utilizing functions like IF, ISBLANK, and NOT, you can easily manipulate and analyze your data in Power BI or other tools that support DAX.
