It seems that gros_postes doesn't belong to you, and its owner didn't grant delete privilege to you (or public) so you aren't allowed to remove any rows. What to do? Contact the owner and ask for some more privileges.
As you aren't referencing it (gros_postes) with owner name, then it might be a (public) synonym, or maybe a (materialized?) view.
Provide some more info if what I wrote doesn't help. For example, what does
select * from all_objects where object_name = 'GROS_POSTES';
