how about data import tool?
which version you are on?
Vendor Field gives you the option to select vendor space, for example you have ARDBC configured for AD, then in this field you will be able to see one more Vendor space to select from dev studio and create the vendor form so that you can access AD data in Remedy.
Same way you need to build ARDBC configuration to access other supported sources.
Please see AR Integration guide.
You can still consume .csv or .dat files with the help of Import tool or AIE.
Thanks for reply.
I want to know how to create a vendor form using external data sources other than active directory ?
As like we have "AR System Administration: Server Information" OOTB form which takes and stores data to ar.cfg.
I am using ARS 7604
You will have to create/write AR Plugin to access external data. You can read more about creating AR Plugins in Integration Guide.
Also for plugin example you can look at https://communities.bmc.com/communities/docs/DOC-2091
Another good sample would be the Twitter integration ARDBC Plugin that Sebastiaan de Man wrote. I found that code really easy to follow when you want to populate a vendor form. Took me less than 20 minutes to spin up a plugin using that code as a sample. You can read about his plugin at Re: Ideas for a Twitter - BMC Remedy ITSM integration. One thing to note is that its a couple of years old; the new location for his code is at https://code.google.com/p/arsocial/
Thanks for your update
