A note on payment eCB (Electronic Blue card) with several articles and several suppliers. The buyer pays the entire Cde by eCB and suppliers regulations separately. In fact, the first flow is accepted and the following are rejected. This is quite normal because the principle of eCB eCB is that the number can not be used q'une once. What can you do to avoid these problems of rejection? Sincerely. G.Bosramier
