Field help (SERNUMSRH) 

If the product is managed by serial numbers at the receipt/issue or only at issue, it is mandatory to enter, before saving the return, one or more serial numbers depending on the quantity returned (this entry is made in the stock detail window).
A control is carried out to verify that the number entered is not already in stock (a serial number being considered as unitary and not divisible).

Upon direct return, it is possible to enter a serial number not known by the system (this corresponds to an old serial number that was not referenced in Sage X3). An information message will report it. Upon saving the return, the serial number is automatically created.

If several serial numbers are returned, the end number contains the last serial number, provided the numbers are consecutive. Otherwise, a '$' symbol will be displayed in the two fields to specify that the numbers returned are not consecutive. It is recommended to access the stock detail window in order to view all serial numbers.
