When you use event OnBeforePost the action is taken before the TIBO_NN object has data changes posted. Each time you change the table used and save the changes a post is done. So the field D.ID is changed each time the table changes.

If D.ID is the primary key for your table and you want a unique key in this field each time you insert a record you could use a "before insert" trigger on the table.

if (new.ID is null) then
new.ID = gen_id(generatorname, 1);
