Symptom
You have noticed that when Sales Orders are created via web shop (web service) the system creates gaps in the numbering sequence of Sales Orders.
Environment
SAP Business ByDesign
Resolution
This is the system expected behavior.
The reason the system is performing gaps within the numbering of the documents is because the numbers are stored within the internal buffering system.
Within the internal buffering system, the engine selects the numbers randomly from the define range to create the documents, however it does consider a chronological order when executing such action.
This logic is applied for both sales orders created from the UI (user interface) and from web service.
