Passing value from one object to another

Hello all,

Here is the situation: In a BEx query I will have a user entry variable for an object 0COMPANY. There is another object 0PCOMPANY that is used in the same report.

I want to accept the same value (that is entered by the user for 0COMPANY object) for the other object (0PCOMPANY) too without entering it separately.

I believe It's not big a deal if I write a custom exit.

But, is it possible to achieve the same goal without writing a custom exit?

Can anyone help?

Thanks,

Pranab
