1. Problems and causes of the application process

1.1 Error: Please enter the buyer or ship-to party

the reason: In fact, there is no buyer on the header of the order, mainly because the field ITM_NUMBER in the sales order partner table ORDER_PARTNERS is assigned to the item number of the sales and distribution voucher. These data are the partners of the project data, so the partner information on the header is missing .
Solution: When assigning values ​​to the sales order partner table ORDER_PARTNERS, the field ITM_NUMBER does not need to be assigned.

1.2 Although the sales order is created successfully, the order quantity is missing

the reason: At first, I thought that BAPI: BAPI_SALESORDER_CREATEFROMDAT2 in the row item table ORDER_ITEMS_IN field TARGET_QTY target quantity can be assigned. If there is no assignment in the plan line, the above situation will occur.
Solution: Assign the order quantity to the field REQ_QTY in the schedule table ORDER_SCHEDULES_IN.

1.3 An error was reported when creating a return order: the combination of business object BUS2032 and sales document category H is not allowed

the reason: This is because BAPI: SD_SALESDOCUMENT_CREATE is called in BAPI_SALESORDER_CREATEFROMDAT2, and the business object business_object in SD_SALESDOCUMENT_CREATE is defined as BUS2032, and the business object BUS2032 cannot create a return order.

Solution: When creating a return order, do not use BAPI: BAPI_SALESORDER_CREATEFROMDAT2 to create, instead use BAPI: SD_SALESDOCUMENT_CREATE to enter

2. Use BAPI to create sales order source code
