File Content Conversion Requirement

Dear Experts,

I have a scenario where PI (7.1) has to pick file from a FTP server and also IDoc data should write on File using FCC in both cases. However the incoming file (fixed lengths) will be in following format without any end-separator, so I would like to know whether the FCC will work for this requirement or not...

usually file with End-separator looks like below...

002 123 2345BBB C

003 231 ADD2213 E

However, in my case the file comes contentiously without any End-separator...

002 123 2345BBB C003 231 ADD2213 E

In the same way, we have to write the file in another interface (IDoc to File) without any End-separator using Append functionality...

Could you please check and give me some idea on this requirement?

Thanks-
Rams
