Your variant is NP-hard by a reduction from, e.g., the 3-partition problem where all values are strictly between B/4 and B/2. It might be "solved" using some of the same methods as capacitated vehicle routing. You have to understand, though, that CPP is less a real problem than an excuse to study T-joins.
