Our company has built customized Tibco interfaces for a client between their applicant tracking system (using Tibco ADB Active Data Base adpaters) and Lawson 8.0 HRIS system (using HTTP request/XML response protocols, i.e. HTTP requests to Lawson forms using HTTP parameters in the URL string)

I'm not a Lawson expert, but I have a couple of questions.

1. Has anyone had experience migrating interfaces to external
systems from Lawson 8.0 or 8.1 to LSF9 and what kind of effort
is involved in doing so?

2. Are external interfaces in Lawson 8.x upward compatible
to LSF9 (I assume not)

3. Are external interfaces to LSF9 now standard WebServices
style interfaces using WSDL's, etc?

Thanks in advance

If you're staying on the same applications version, then I would qualify the effort as medium. The DME / AGS calls syntax changes between versions, but since the data structures you're working with are the same you shouldn't have too much trouble.

I would also recommend you leave some time to discuss security. LSF9 security has a flag called "Access", which controls if you can access data not associated with your employee number. We had to set this to "yes", even using laua, to get access to tables that didn't have employee number in it (say, like PRSYSTEM). That opens up a back-door security whole for anyone who knows how to structure a DME call.

I believe implementing LSF9 security would close this whole, but it was not within scope of our project. You could always have your interface(s) run under a specific users that uses LSF9 security to eliminate this problem, but either way leave time in your project to be trained, expirement and TEST.
