re-use existing mapping to remove line breaks between appended files...?


Hi All,

Finishing up my remove header/trailer in a flat file to flat file project using java mapping and content conversion.

Multiple outbound files in with a single inbound file using the append functionality in the receiver comm channel.

Mapping and conversion working perfectly, Inbound file arrives in needed format but with blank line separators between the sets of records after appending. I need these lines removed so the single inbound file is seemless and can be processed by the back end. My existing mapping eliminates any detail row less than 20 characters (both header and trailer contain less than 20 chars) and concatenates them all for the inbound file.

It seems the best idea to move forward would be to use my existing mapping again for the file (after its initial append) that will eliminate any empty lines and spit out the final product. Is this the best scenario to use? If so I'm thinking that the existing map would do the same work again. I would copy it over and rename for fault reasons, of course, but in theory I think I'm on the right track.

In a nutshell


File2 --->mapping to remove header/trailer >appendfiles ->intermediatefile >remappingtoremoveblanklines >final product


Any theologians care to comment on this one? Am I on the right track?
