Mostrare nella My Inbox di Fiori gli allegati delle RdA (ME53N)
L'APP standard My Inbox di Fiori, normalmente permette di visualizzare e fare il download solo degli allegati inseriti in Business Workplace.
Implementeremo del codice per fare in modo che l'APP, consenta la visualizzazione/download degli allegati inseriti nelle Tcode ME51N, ME52N
Richiamare la tcode SE18, e ricercare la badi WF_OBJECT_ATTACHMENT
Fare doppio click su implementazioni, e nella schermata di dx fare doppio click su MM_PUR_PR_WFL_ATTACHMENT
Fare doppio click sulla classe a sx, e nella schermata di dx fare doppio click prima su IF_ATTACHMENT_PROVIDER_BADI~GET_ATTACHMENT_LIST (per fare in modo di visualizzare gli allegati nella My Inbox) e poi su IF_ATTACHMENT_PROVIDER_BADI~GET_ATTACHMENT_CONTENT (per gestire il download degli allegati)
