I am requesting this enhancement for my client Bridgestone Firestone USA. They are currently using Sterling Integrator 126.96.36.199 and are experiencing many issues with ".tmp" files and SFTP/FTP. Some of their trading partners send in large files and have their SFTP clients configured to name the files with a ".tmp" extension while transferring, then renaming them to the "real" file name without the ".tmp" sometimes if the transfer stalls slightly and the file becomes stable, the SI MailboxRrouting Rule triggers and executes the processing Business Process. At the time of execution the ".tmp" file has been renamed and they get a "Mailbox Message Not Found" error. The issue has been fixed in File Gateway with a customer override in "customer_overrides.properties" like this: äóìfilegateway.ignoreFilename1=.*[.]tmp$äó, this works fine in File Gateway but it does not work in Sterling Integrator Mailbox Routing Rules. I would like to request an enhancement to implement this functionality in Sterling Integrator Overrides so that these äóì.tmpäó transient files are ignored by the routing rules in the same way. File Gateway posts a warning äóìFG_0424äó äóñ äóìArrived File is now Ignored due to Filename Pattern .+[.]tmp$.äó When the override functions to ignore the äóì.tmpäó file. Could this enhancement be included in the next release?
