Our client has such demand for so number range, sale order number starts with letter and follow up with numbers for internal assignment. likewise 'AB123456' . how to achieve this goal? could anyone share some ideas?
adding to solution proposed by Mr. Jignesh Metha, don't forget to tell your abaper to consider how system will react when you reach latest number of your range , what will be next number, for example for range from AA000000 to CC999999, when you reach AA999999 next should be AB000000, not AA000000 which be duplicated.
It will not be possible to have alpha numeric number ranges for Sales orders through SAP Standard Automatic Number Range maintenance.
One option is external number ranges, but I understand this is not practical for Sales order.
Another option is to go for enhancement & insert a ABAP code in User Exit USEREXIT_NUMBER_RANGE in program MV45AFZZ.
The program will refer to a Z-Table where the required number is maintained. Please speak to your ABAPer on this & he will do the needful.
