Is there any way we can processing multiple sales orders in sales order create service.
AIF inbound processing in AX 2009 we can have one sales order per XML.
I am in a situation processing multiple sales orders
It is possible in AX 2012
This can be achieved through a staging table and wrap before SalesTable.
Your assumption is wrong - messages for AIF document service can contain more than one entity. Your problem must be somewhere else.
In 2009 Sales order service you can receive only one sales order per document. Because hierarchy in AxdQuery is SalesTable. If you want to receive more than one salesTable you have to have staging table wrap to your query
