Total record count from Attribute View

Hi All - I am new to HANA and tried to build something very simple.

1. I created one attribute view by joining Billing tables , VBRP and VBRK , Header and detail table.

2. I joined both the tables with VBELN - Doc number.  Used referential join ( VBRK is on left and VBRP is on right side)

3.  Checked and activated the View.

4. when I try to run select count(*) from attribute view ,  I am getting some very high number of count which is no where close to VBRK and VBRP.

I am confused how come view can return huge number of records.

Any thought ? Experts.

Regards,
