We are using PI for one of our scenarios as simple File Transfer. We are using NFS to pick .HDR and .ZIP files and send it across using SFTP adapter.
The requirement is such that the .DTA files must first be written followed by HDR. The size of the .HDR is just 5kb whereas DTA files is relatively huge ranging from 24-50MB.
The only choice I have is to use two communication channels and schedule it with different timing. Since it is going to run once a day, I can schedule one channel to pick up DTA at 10:00, after an hour will schedule it to pick up HDR.
Let me know if you guys have any other suggestions on this!
