Method and device for acquiring material changing range

Abstract

The invention provides a method for acquiring a material changing range. The method comprises the following steps of: 102, acquiring material groups which are quoted for changing materials; and 104, when a user selects from the material groups, supplying all materials quoting the selected materials in the material groups and all materials quoted by the selected materials to the user, and taking all the materials as a changing range needed by the user, wherein the materials can be quoted directly and indirectly. The invention also provides a device for acquiring the material changing range. By the method and the device, all the materials influenced by changing the materials can be acquired, and a range can be provided in an intuitive way for a user to specify the changing range.

Description

technical field [0001] The invention relates to the fields of material management and product structure information management, in particular to a method and device for acquiring material change ranges. Background technique [0002] Enterprises that use the PDM (Product Data Management) system for material and product structure data management, when changing a material, especially a material that is referenced by many BOM (Bill of Materials), often hope to know the scope of influence of the material change . When solving this problem, the prior art generally can only find the BOM that directly references this material, and presents the BOM collection that directly references this material in a table or other non-intuitive ways. [0003] The above method cannot allow users to truly obtain the scope of influence of a material change. When the BOM that references the material is referenced by other BOMs, this indirect impact cannot be displayed or obtained through this method,...

[0003] The above method cannot allow the user to truly obtain the scope of influence of a material change. When the BOM that references the material is referenced by other BOMs, this indirect impact cannot be displayed or obtained through this method, that is, the BOM references at various levels cannot be displayed intuitively. The full change impact domain of

Moreover, when the materials before the change and the new materials after the change need to exist in different BOMs, then it is necessary to determine the scope of the relevant changes, that is, which materials on the BOM will be replaced with the changed materials, and which BOMs will be replaced The material does not change, and the directly referenced BOM is displayed in the form of a table as the basis for selecting the relevant change. The scope of the indirectly referenced relevant changed material that cannot be fully displayed is prone to omissions in the selection of the relevant material change range.
