We compute RR charges of D2-branes on a background with H-field which belongs
to a nontrivial cohomology class. We discover that the RR charge depends on the
configuration of the background `electric' RR field. This result explains the
ambiguity in the definition of the RR charge previously observed in the SU(2)
WZW model.
