Hi Richa,
Please check a couple of things.
1) Check the Scheduled Actions assignment block on the normal change and review the action to import to production. One or more should be red with error. Check the action log for those. This may or may not tell you more information. Also look to see if you have any other actions that had errors. It may be a prior action that failed that is causing your issue.
2) Check the status for the normal change by running program crm_order_read from sa38 and check the ET_STATUS data, looking for an I1030 status which is an error status. If you have an I1030, that may be keeping you from changing the status of the normal change. You can remove the I1030 error status by executing a SAP provided program as documented in note 1911047. Note that you should only do this if no other way can be found to resolve your issue.
Kindest regards
Paul
