How to store the file structure and get the structure in PI

Hi All,

I am working on File - RFC Synchronous scenario. My requirement is I need to store the entire file request before sending to RFC.And I have need to send the request and response to File. We are working on PI 7.31 Dual Stack.

I have to store the whole file structure and should get that structure.

Please let me know the possible ways how I can store and get that.

This is my first scenario.Please let me know if my requirement is not clear.

Attached is my file structure coming to PI. As mentioned in the attached structure, header is 1..1 cardinality and item is of o..n cardinality.

Thanks,

Swapnika
