s233, if the existing process is adopted, the original special function number is selected, and the original process can be used; if the process is not the existing process and needs to be newly added, automatically generating a special function number;
and S234, receiving the required material information and the required process information in the required editing information recorded by the special function number, and generating a special customized BOM table and the process information.
9. The method of claim 1, wherein the step of integrating the base BOM table and the model selection to obtain a customized BOM table and a production process route comprises,
deriving a customized BOM table:
calling a type item BOM table, a type selection constraint BOM table and a special customized BOM table, extracting and integrating information required by a current type selection client, and finally combining the information into a customized BOM table;
generating a process route:
s241, extracting and identifying all process nodes in the process route, and extracting the process nodes which influence or determine the model selection items of the process route as the process nodes required by the configuration of the model selection items;
s242, acquiring a whole set of model selection configuration information items through a model selection analysis process, and then linearly integrating process nodes related to model selection to construct a process route to which a model selection product belongs;
and S243, sending the information to an internal production and manufacturing execution system for executing the process.
10. The method of claim 1, wherein the step of creating the base BOM table comprises creating a map frame and filling the map frame with fixed base BOM information to form the base BOM table.
