Head Office account in FBL5N

Hi there!

We have an head office account. When we viewed it in FBL5N with the following paramters: Customer, Company code and Open item as of xx.xx.xxxx. The result of which for example is 50000USD. Then we tried to use FBL5N but with different parameter. We select from the dynamic selection - head office and indicate the account, open item as of xx.xx.xxxx. The result was 35000USD.

Can you provide possible reasons why the result is different?

Thanks a lot.
