How have you defined your itab ?
You query looks perfectly ok , even if you use vbeln or vbelv it wont matter , it depends on the requirement.
So have you defined your itab correctly ?
for example :
data : begin of itab occurs 0,
         vbeln like vbrk-vbeln,
         kunag like vbrk-kunag,
         netwr like vbrk-netwr,
         ntgew like vbrp-ntgew,
         matnr like vbrp-matnr,
         erdat like vbfa-erdat,
         end of itab.
