Hello,
You can use the BAdi BOM_EXIT method like CHECK_PLANT_AUTH_IN_GROUP_BOM or BOM_DATA_CHECK with your own logic.
Assign authorization C_STUE_WRK = ' ' to the desired users.
Also refer SAP note 1109288 - Function modules for bill of material authorization check
which have given new function modules for authorization checks:
BOM_AUTHORITY_CHECK
BOM_PLANT_AUTHORITY_CHECK
