When you delete an associated requirement in Rational ClearQuest, the integration feature attempts to clear the Rational ClearQuest integration attribute values in the corresponding Rational RequisitePro® requirement during the next refresh operation. The attribute modification fails if you do not have adequate permission. A failure is recorded in the refresh_error.log file.
See the help in Let's Go Rational RequisitePro and in the Rational Administrator for information about the refresh_error.log file. In Rational Administrator, right-click a project that includes an associated Rational RequisitePro project and Rational ClearQuest database, select RequisitePro-ClearQuest Integration, and click Help in the integration wizard.
