How to execute a formula when a record is deleted?

[FSuarezJimenez]

I have two entities related one-to-one. I want that, when I delete a record from entity 1, the related record from entity 2 is also related.

I could do this:

 record\update(ENTITY2, ID, 'deleted', true);

but my problem is that the formula is not executed when I delete a record (with the GUI), any idea on how to do it?

Your code should work, but here is the part missing, as when this should happen. I guess, you will need a ifThen formula with your formula in the "Then" part:

ifThen(
record\update(ENTITY1, ID, 'deleted', true);
record\update(ENTITY2, ID, 'deleted', true)
);
