how to retrigger Property calculator calculation rule?

There is a function to update Objects in Property Calculator under Background Operations, maybe this helps:

If it's the name, you can use recalculate function of the admin tool. If you right click the class, there is an option to recalculate names. It will ask you to go for empty ones or everrything, then, does the relcalculation.

Couple things to check before going for it

• If you go for recalcuate everything and the class has too many objects (thousands or more) it will take time
• check if you have objects in the class that has no value on a required field. This will halt renaming 
• be sure that you want everything in that class renamed.. as that is exactly what that will do
• check your code or naming scheme is well thought on every possible combination

Thanks It was exactly I was looking for, I didn't checked that part of the comfig.

Hi Guillaume,

You’re on the right track. Unfortunately, Property Calculator (PC) rules typically trigger only on creation or when a relevant property changes — so to "retrigger" a rule, you'd usually need to force an update to the dependent field.

One workaround is to batch update the related field with the same value (using a script or manual bulk edit), which should retrigger the calculation rule. Another approach could be to use automation (like a workflow rule) to simulate a change and fire the rule again.

By the way, if you're dealing with formula logic or educational tools that support structured calculation, you might find something like Calculadora Alicia helpful — it's a free online calculadora secundaria designed for students and educators, but its interface is also great for testing out basic calculation workflows and logic.
