I'm in the process of coming up with a plan for importing information from an HRIS data source on a schedule through the system. I am also planning to do an import from other sources manually through the HR import process (less frequently and for users not contained in the HRIS data source).
The automatic imports will have record ids that are generated at the source. The manual imports will have record ids that are generated in house by our own programs that would compare existing information with the contents of the files. My plan is to have a custom id containing alpha characters followed by sequential numbers to keep the ids unique enough that they will never interfere with the main imports. It is my understanding that as long as these record ids don't change or match those from the other import that we can do both import methods, multiple files/sets but only one set at a time. Am I correct?
Has anyone done this before? Any suggestions on best practices, etc., would be appreciated.
