You can use stored procedures when you create an EF model, to map your entity sets to tham, see for example "How to: Define a Model with a Stored Procedure" (http://msdn.microsoft.com/en-us/library/bb896279.aspx). Then you can use those entity sets in C1DataSource and in SEF in general.
I have this case:
a stored procedure named Humans with parameters JobID and ReadinessDate and i have a complex type for this named: HumanResults.
How can i use c1datasource or direclty scope.getitems with this?
Can you give me an example please?
