Summary :
In SAP systems, BOMs that are deleted using a change number remain in the database physically due to the system's logic, which performs a logical rather than physical deletion. To address this, users with specific permissions (via authorization object C_STUE_NOH with field NOHIS set to 'X') can perform a physical deletion. This process involves using the transaction dedicated to changing BOMs, allowing for physical removal of BOMs, including those that normally require maintaining a history.
