The SAP error message O8842 indicates that a product has already been loaded through a specific meter, and therefore, deletion of that loading is not possible. This error typically occurs in the context of logistics or inventory management, particularly when dealing with loading and unloading processes in SAP.
Cause: Existing Load Record: The primary cause of this error is that there is an existing load record associated with the product and the specified meter. This means that the system has already registered the loading of the product, and it cannot be deleted without first addressing the existing record. Data Integrity: SAP enforces data integrity rules to prevent inconsistencies in inventory and logistics data. Allowing deletion of a loaded product could lead to discrepancies in inventory levels and tracking.
Solution: Check Load Records: Review the load records associated with the product and the meter in question. You can do this by navigating to the relevant transaction
