Hi Meghana
You will have to assign BA scenario to Ledger, it applies to all countries. But as long as you dont make it a mandatory Characteristic for Doc Splitting, it should not harm anyone
For Sequential numbering of documents, I am not sure if this is legal requirement in China. It is there i Italy
You need to have a Z Table wherein you maintain no. ranges per Doc type and Business Area and derive it from there using user exit
