Quality inspection code is set in MMS001 – item master.

M3 does not allow to change this setting if planned transactions exist for goods receipt into stock only, for real, firm Purchase or Manufacturing Orders.

System planned transactions are ignored (tested).

MMS002 can be consulted to see in which warehouse an item is used.

Planned transactions can be consulted in MMS080 for each warehouse.

Order Category (OCT) ending on 1 concerns real, firm transactions.

OCT ending on 0 concerns system planned transactions (can be ignored).

In this example there is a record with OCT 111 => this concerns material issue, for material that will be used as an ingredient. Is not a receipt in stock => can also be ignored.

Order Category 101 or 251 concerns real MO- and PO transactions => if those still exist in any of the warehouses, M3 does not allow to change the quality inspection code.

Those should be fully reported or deleted, before M3 allows to change the inspection code.

Same for DO planned transactions OCT 501 and 511, also should be fully reported.

After doing so, M3 allows to change the quality inspection code (set from 0 to 3-requisition).
