Backend creation of user for Apps
i wanna know how to create a user (for say having Financial or HRMS resposibilities) from backend.....i read that for doing the same i should have all info abt API's ....why and how will i use them (APIs)?? and will it be possible if i want to allocate that user with a separate set of memory (may be putting him in a different tablespace....i guess)........???????????
