BADI ME_PROCESS_PO_CUST - DOES NOT CLEAR OUT ERROR

Question

In ME21N I want to validate the field Commodity Code - STAWN. I have used the BADI ME_PROCESS_PO_CUST*
. Have used get_foreign_trade() in the PROCESS_ITEM method . I am able to throw an error . It is doing it but*
after throwing error then when we give a valid Commoditycode too it is still showing the error and not clearing the error  .*
As suggested by Dean Q I used   INCLUDE mm_messages_mac,
tried im_item->set_foreign_trade( ls_mepo_eipo)  still when a valid Commodity code is entered after an invalid one  it does not clear out the error. In fact on checking using break-point I found that the second time it does not enter into the method  PROCESS_ITEM.    Any help is welcome

Hi,
In SE18 give ME_PROCESS_PO_CUST as the enhancement spot and display. At the left side of the screen you can see the badi definition ME_PROCESS_PO_CUST. Expand the tree and double click on implementations. You can see the enhance implementations created. Double click on the enhancement implementation and in that screen there is a check box 'Implementation is active' and field 'Effect in current client'.
If you know the enhancement implementation name(not the badi implementation name), you can check it directly from se19.
