Hi Martin,
you might also receiving Bank statement files through SWIFT channel in your network directory.and i assume you have PI / XI also there in your environment.
so, you can setup a RFC channel and also can write one program / to call FF.5 transaction.
so, RFC Channel will pick the file from network directory will auto call program of FF.5 and FF.5 will process the file.
now next problem will come that this program gets terminated in between sometimes as in FF.5 it is not able to differentiate warning message /Error message/ information message. so, for that for known warning message which you know that it is no harming bank statement processing , you can choose ignore by adding it in T001S / T001K table by selecting Message class of that message.
and also what i have done is following auto upload of a perticular file, i have setup a Mailing functionality, which can send mail to receipients after executing FF.5 and its status. for that after FF.5, the message gets stored in some internal Table. so, ABAP Program picks the latest message for that file.
all mail recipient will get mail for success / failure. you can cross check that directly in FEBKO Table also after processing of same file, if it got uploaded or not.
have done similar implementation and we are uploading daily 100+ files.
Hope this will help you also.
(kindly give points if answer is helpful)
