Hi ,

When user submit if user id already exists in sys_user table ,it will create other than that .

You can create a insert business rule on the sys_user table. Any logic can be added over there.

is it on catalog form or on table ?

you can write here glide ajax to validate if username combination already exist on sys_user table or not and based on that set the value .

can you help with that how i can create or validate user id already exists or not ?

And on that basis how i can create new user id ?

You can create a after insert Business Rule or onSubmit client script. If you only want it to work for new record add condition current.isNewRecord() or g_form.isNewRecord()
