SDV1 - Expiring contracts error

Hi ,

I am using standard SAP report to get a list of expiring contracts in T code SDV1.

I am using only the date to find the contracts which will expire until that particular date but I see that the report is displaying all the contracts even if an order reason is maintained for the contract.

I believe that if a order reason is maintained for a contract then that contract should not be displayed in the report and is it a correct assumption ?

Can anyone tell is this standard SAP behaviour.

If no then what is the base logic on which these contracts are displayed in the report.

Regards
