WW053 - Details

• The SAP error message WW053 ("MG / plant allocations exist. Deletion not possible") typically occurs when you attempt to delete a material master record or a related object, but there are existing allocations or dependencies that prevent the deletion. This is often related to the material being assigned to a plant or having stock, purchase orders, or other transactions associated with it.
