F.01 Report

Hi

I do have a strange problem. At F.01 whenever I run the report for Chart of Accounts ABCD,company code ABC & income statement CC02 the result is good.We can see the groupings and at the end of the summary there is income/loss for the company. But in case of COA WXYZ, company code XYZ & income statement CC02 no matter what ledger we select, we don't get any income summary. What can be the reason?

Regards
