When creating TO, I sometimes want to input the External Alphanumeric in destination SU.
I setted that SU number range assignmnet is 3 [Int.+ext.number assignment and use of prev.numbers] and Conversion of storage unit numbers is 3 [Customer-specific user exit].
I can't manage SU. Although i input new SU, system clears it. So TO has no SU.
Let me know how to fix it.
Thank you in advance.
