and when traversing the self-made part with the code number prefix of Ka8, creating a process splitting piece, acquiring the map number attribute of the version of the self-made part corresponding to the EBOM, wherein the process splitting piece inherits the attribute information of the part before original splitting and associated pattern model data, adding suffix identification to the name and the map number of the splitting piece generated when creating the splitting piece, and building the name and the map number of the splitting piece to the next layer of the corresponding part in the BOM.
9. The EBOM auto-conversion system according to claim 6, wherein the structure editor comprises:
and reading the design attributes of the three-dimensional product design model corresponding to the EBOM, comparing and verifying the configuration part attributes of the initial PBOM with the design attributes of the three-dimensional product design model, and obtaining the final PBOM after verification is passed.
10. The EBOM automatic conversion system according to claim 7, wherein the first processing unit performs automatic matching conversion according to material coding to generate the initial PBOM.
