Symptom
A material is created with a material type that does not have purchasing view in the material master (e.g. FERT). Nevertheless, the system allows to create purchase order (PO) for this material and follow-on documents as well, because system message "Material & not maintained by Purchasing" (ME046) is not raised at PO creation.
Environment
SAP S/4HANA Cloud
Cause
In SSCUI 103539 "Define Attributes of Material Types", the purchasing view is not activated for the material type. The message ME 046 is only raised if the Purchasing view is active for the material type in this SSCUI and the view is not maintained in the material master for the material.
Resolution
If you want the error to be raised, you can activate the purchasing view in SSCUI 103539 "Define Attributes of Material Types".
If you do not activate the purchasing view in this SSCUI, then -as a possible workaround- you can block PO creation with system message "Material & mainly procured internally (please check your input)" (ME 092) - the issuing of this message depends on the setting of the field "Procurement Type" on the MRP 2 view of the material master.
