Hi @El Cuchi ,

Apart from what @Chaitanya ILCR mentioned that you may need to check the BR condition if gs.isInteractive()  is added which means it will ONLY work if a logged in user initiate a transaction and not for any integration,

If you are using import set API and getting the records updated through transform map, then please verify if 'Run business rules' is checked in the respective transform map. If that is unchecked you need to check that.
