  The SAP error message CY381 ("Order & could not be locked") typically occurs when there is an attempt to access or modify a production order that is already being processed or locked by another user or session. This can happen in various scenarios, such as when multiple users are trying to edit the same order simultaneously or when a previous transaction has not been completed properly.
