the latest way of creating serial item start from real 13,
- need to have the item in the ware house location with the option "serial numbered model" set to YES
- need to have a item in the Serial location call "Serial.No.here"
- the "Serial.No.here" item need to have the option "serial numbered item" set to YES
- when receiving item in the ware house location , for a serial model, an serial will be cloned from the "Serial.No.here" and have the model code put in to the associate stock code,
- if the S category of the model code exist in the serial location (e.g. cat = 0201 , cat in serial = S0201), that S category will be used in the cloned record, so for the phone to work need to cerate same cat in the serial location.
