Dear,
08 inpsection type has been defined for the same.I presume that you are doing stock posting through MB1B/MIGO t code & 311k mvt type.
Check the following setting
Qcc0->Quality Inspection->Inspection lot creation>Inspection for goods mvt->Deactivate Quality Inspection for a Movement Type--> check here whether for 311k QM mvt is deactivated here.
Regards
Aniket..
