Integer Field Comparison in Validation Rules Not Working as Expected

Hi Oracle Community,

I’ve created two custom properties in Oracle Field Service: activity.XX_INT1 and activity.XX_INT2, both set to Integer type.

In the validation rule for XX_INT2, I’m checking that its value is greater than XX_INT1 using:

this > activity.XX_INT1

What’s happening:

This doesn’t behave as expected. For example, with XX_INT1 = 46:

• Entering 1, 2, 3 → validation fails (expected)
• Entering 5, 6 → validation passes (but 5 is less than 46)
• Entering 111, 123 → validation fails (but 111 is greater than 46)

However, if I write the condition like:

this > 46

…it works exactly as expected.

Question:
Is there a supported way to perform true numeric comparison between two Integer-type fields in OFS validation rules?
