Thanx for your reply i know excactly witch step (the last one, the one witch send the workitem in the bwp). the biding seems correct to me for that user us+name = 13 and should be enough...
this how the step works
begin_method zwfdetbuyer changing container.
data:
ebeln type ekko-ebeln,
buyer type wfsyst-initiator, "buyer TYPE usr02-bname (ticket 3202),
err type pmflags-flag01,
bnome type adrp-name_first,
bcognome type adrp-name_last,
emailbuyer type adr6-smtp_addr,
flag.
swc_get_element container 'Ebeln' ebeln.
call function 'Z_WF_DET_BUYER'
exporting
ebeln = ebeln
importing
buyer = buyer
err = err
b_nome = bnome
b_cognome = bcognome
email_buyer = emailbuyer
case sy-subrc.
when 0. " OK
when others. " to be implemented
endcase.
swc_set_element container 'Buyer' buyer.
swc_set_element container 'Err' err.
swc_set_element container 'BNome' bnome.
swc_set_element container 'BCognome' bcognome.
swc_set_element container 'EmailBuyer' emailbuyer.
end_method.
if i check the FM with the username the buyer name is correct.
