How to use different data set in rdlc (Report viewer)

Hi.

I need to design the Order Form.

Two things I need to display in the Order form.

1. Order Number : 03  -->(This 03 is comes from a table. I have get this using table adopter say OrderNumberTableAdopter in OrderForms.XSD file.)

2. Item Details. This I get from the difference SP. I get the item details from the Table Adopter which i used in the same OrderForms.XSD.

How can i assign this two results to the rdlc 

Please let me know if this is not clear.

Thanks.
