Question related to FILE SENDER handling of recordsets

Hi

We have a File->RFC SAP scenario

We are reading files using FTP File adapter. Splitting messages 100 messages per recordset. QOS is EXACTLY ONCE!

If we have a huge file - lets say 100.000 records.

The adapter starts reading and gets to 50.000th record and FTP server (SENDER) crashes.

My question is which one of the below scenarios is true (if any):

A)

are those 50.000 records now processed, and in "chunks" of 100's beeing routed to the SAP system and processed?

What then, if the FTP server comes up again, how does it know where in the file it has reached???

B)

Or is it so, that PI reads the file and persists the messages (in 100's) and only when it has reached the end of the file it then

starts to call the SAP system via RFC adapter.

If it does NOT reach the end of file (ie FTPserver crashes...) then ALL messages (so the 50.000) are marked as erronoeus and will NOT be processed to SAP RFC?

I hope it is B, but please help
