Error Handling in B2B Composites

Question

Hi B2B Experts,
I have a composite in which i do a B2B Inbound Operation. I receive a custom PFF protocol Remittance file from one Business Partner. After i get the file, i will be creating receipts for the invoices i get in the file. My file has one header, many details and one trailer. The file has like around 800 details. So, i need to follow the same business logic for all the details may be looping them inside the while activity. So, can one BPEL instance handle like 1000 iterations of the while loop and how should i handle the errors inside the BPEL. Like let's say if something was not processed successfully for any of the detail record. I can write fault policies, keep catch and catchAll's, send emails as required. Please help me with the correct approach.
Thanks,
Naresh

I would suggest you put while activity in a scope and catch expected fault [ say remote fault ] in it
write your policy to retry the activity in the while in case it fails . you can give retryCount and retryDelay
in case after all retries your while activity fails and throws a fault then catch this fault in main scope
