Require to change Person Type in Employee form automatically by changing of Assignment status, currently HR is changing manually through Person Type Usage. I would like to know that is possible without customization and through personalization can it be done?
Doing this on a automatic basis might be difficult but you can schedule some concurrent program which will perform this action on a daily basis.
The program will first pick all the records for which the require change has happen in assignment on that day.
Then it will perform a bulk-update using API to change the user person type.
