Dear all,
I have a sample of companies that are subject to different tax rates,
they are owned by different parent companies. I would like to compute
differences of tax rates within each group and in the perspective of
each company. Below is an example of the database and a view of what I
would like to compute:
group company taxrate
1 A 15
1 B 10
1 C 20
2 D 20
2 E 15
2 F 14
2 G 30
The task I need to do is calculate the following regarding for
instance companies A, B and C of group 1:
A=> (15-10) + (15-20)
B=> (10-15) + (10-20)
C=> (20-15) + (20-10)
As I have thousands of companies it is a hard to do this manually, is
there any suggestion on how to handle with this calculations?
I would appreciate any help.
Best regards,
MJ
