Several factors can prevent an article from being ordered in Lean Catalog. First, the system considers both plant-specific and cross-plant statuses from the SAP material master, which can be used for discontinuation control based on your shop definition settings.
Additionally, items are automatically blocked if a supplier material's validity has expired or if the price is no longer valid for the current date. As an editor, you can temporarily or permanently lock a product using transaction /ESAP/CATMAN. Within this catalog management tool, you can set a lock for any catalog item or apply the No Order indicator.
In the following demo, you will see how to adjust the validity of a supplier material and how to manually set a lock.
