Cancelled Confirmation

Pleople

I did the confirmationof hours through COR6N and after a cancelled this confirmation, but in transaction

COR3 -->GOTO --> Costs -->Analysis don´t show the line related of cancellation. The report show only the positive quantity, but should show one line with negative quantity of cancellation.

When I do duble click in the line (positive quantity) the SAP open the confirmation (CORT) and show the confirmation and the field "Cancelled" is fleg.

The same situation occurs in the CO reports KOB1 and KKBC_ORD, they don´t show the negative hours of cancelled confirmation.

I check the table AFRU and the documents are corrects.

Please, someone have any suggestion of what can be?

Regards
