Method and device for realizing multiplexing of module-level codes in BOM of different products

The invention provides a method and a device for realizing multiplexing of module-level codes in BOMs of different products. The method comprises the following steps: changing a module-level mounting specification-level mode in an existing module-level BOM from a fixed mode into a selectable mode; adding product selection attributes to the attributes of the specification levels of the module level mounting, and adjusting the number of the specification levels of each module level mounting; when the application state of a certain specification level material in the product needs to be changed, changing the front-end execution environment of the modular BOM, identifying the specification level material number of the product level, and changing the application state of the specification level material of the specification level material number under the corresponding module level; when the modularized BOM is created, when products of the same generation batch exist, applying a module-level material code for the
