Diagnosis
If you activate Empties Management in the component MM, you can workwith an extended dataset.
Note:
If you later deactivate Empties Management in the component MM, it couldcause inconsistencies in the dataset for the Purchase Order andLogistics Invoice Verification.
Background:
The Structure Category for Material Relationship field is used todifferentiate between full products and structured emptiesand normal materials. The structure category together with the functionof the bill of material (use 5) causes the system to show tied emptiesas dependent items in the purchase order. The Structure Category forMaterial Relationship is also used in the Invoice Verification area.
