logic query

hi frnds,

sales doc no-VBAK-VBELN-parameter in selection screen

sales doc category-vbtyp for only 'c'(order) and 'g'(contract)

sales doc header-vbak

billing doc header-vbrk

how to write a query for this selection--

If the user enters the sales document number, perform the selection to see if the entered document is sales document

or contract or billing document by comparing sales document category in sales document header or biling document header.

tnx
