Summary :
When creating a production or process order in SAP, error C2231 may occur if a component's storage location is missing from the material master, production version, or BOM, preventing master data transfer. Customizing settings might also trigger information message C2195. Resolution involves verifying the component's status: if it’s not a phantom assembly, the storage location needs to be established in the material master; otherwise, for phantom assemblies, this step is unnecessary, and an information message will be displayed instead of an error. Relevant transaction codes include CO01, COR1, CO40, and COR7.
