Hi Praneeth,
Please check all configurations of release strategy in QAS server & compare it is same as Development server or not .If it is not same then ask Basis team to transport request again in QAS server.Also check characteristic values in CT04 & also check in CL24N Characteristics values(Plant & document type) has been maintained correct or not.Also check document type configuration there is tick on overall release or not, if not then tick mark on overall release.
Reward if helpful.
Thanks
