Webservices over File
We are using file system to bring the files in ECC via SAP PI. This system is secured ( SFTP) and works fine.
ECC is run on batch mode nightly, where all jobs runs in night, pushes data to PI ( proxy, IDOC) and then PI pushes the data via File ( SFTP) to third party.The pull mechanism is same where PI pulls the data in stipulated time and then provides in form Proxy, IDOC to ECC.
For new ingratiation to third party, we are debating weather to go for SOAP or continue with file bases system.
Since we are batch driven shop, there is no need to call SOAP ( which i think is mostly for real time). Also volume of data is another concern.
Since we push the data once in night, we are not sure if SOAP can handle huge volume. Also if there is connection failure to this party system, PI via
file system pushes/pulls every 2-3 mins. This system ensure there is no human involvement and once the third party system is up & running, the integration is back online.
Can you advice from above what would be the advantages of using SOAP over File based.
We are covered for security as we are using SFTP as well private VPN for connection to third party.
