Déclenchement d’un workflow avec les messages
Pour déclencher un événement à partir des messages (NACE), il faut
Business Workflow / Développement / Outils de définition / Evènement /Génération d’un événement / Pilotage des messages ou transaction NACE .
Puis vous devez choisir l’application concernée (pour moi EF, pour les commandes d’achat).
Pour ma part j’ai fait une copie de ce programme pour pouvoir transmettre la clé du message afin de le placer en erreur si jamais mon workflow connaissait un souci.

Si l’évènement est lancé alors le message est considéré comme réussi, voila donc ma méthode si le workflow ne réussi pas pour placer le message en erreur.
Pour mettre le message en erreur au cas ou le workflow ne fonctionne pas
data : ls_nast type nast,
lt_nast type table of nast.
call function ‘RV_MESSAGE_SELECT_SINGLE’
exporting
pi_nast_key = ME->GS_NASTKEY
IMPORTING
PE_NAST = ls_NAST
* EXCEPTIONS
* RECORD_NOT_FOUND = 1
* OTHERS = 2
.
append ls_nast to lt_nast.
if sy-subrc <> 0.
* Implement suitable error handling here
else.
call function ‘RV_MESSAGE_SET_PROCESS_STATE’
exporting
msg_vstat = ‘2’
tables
msg_nast = lt_nast
* EXCEPTIONS
* NO_UPDATE = 1
* OTHERS = 2
.
if sy-subrc <> 0.
* Implement suitable error handling here
endif.
endif.
endmethod.
