         Hello,

        I have to transfer files from a host application which writes several ASCII (non XML) files to a subfolder structure. If all files for one subfolder are written, the host creates a trigger file to signal that the files are now ready for transfer.

         

        Sample:

        folder1\

                    file1.txt

                    file2.txt

                    trigger.txt

        folder2\

                    file1.txt

                    file2.txt

                    file3.txt

                    trigger.txt

         

        The files can he handled as flat file and no disassembling is necessary from my side.

        The trigger file should be removed after processing the last file of the folder.

         

        My question is how to handle this !?!?!?

         

        Thanks in advance

           Hello All,

          Maybe my previous question is a stupid question, but I would appreciate if someone gives me a comment about this [:)]

          Thanks
          Hermann

              I would look at creating a batching orchestration that uses a sequential convoy pattern.  The batching orch can receive the files in a loop.  The loop should contain a listen shape with two receives: one receive for the data files and one receive for the trigger file.  You can differentiate between the files using file masks on the receive location.  Receiving the trigger file should break out of the loop and continue processing.  It would be nice if you could somehow delay BizTalk from consuming the data files until the trigger file arrives.  BizTalk doesn’t work that way though, so you need to use a batching orch.  Otherwise, BizTalk will see the data files as unexpected and will throw an exception.

                   Russel, Thanks for your reply.

                  I will try it on this way.
