Description

Templated purchase file generation method and system Technical Field The invention relates to the technical field of computer information, in particular to a templatized purchasing file generation method and system. Background In the field of purchasing management, especially in the operation of large enterprises or clustered companies, standardization and standardization of purchasing flows are key to improving efficiency, controlling risks and guaranteeing compliance. Purchase files, such as purchase announcements, purchase invitations, review reports, transaction notices, and the like, are the core carriers and legal basis for the purchase activity. These documents are of a wide variety and their content, format and terms often need to be strictly customized according to different purchasing means (e.g., public bidding, competitive negotiations, etc.), project types, and management regulations within the enterprise. At present, in the traditional or informatization-less purchasing management mode, the following modes mainly exist in the compiling of the files: (1) Manually compiling, namely, the business personnel completely rely on manual operation to write each purchase file from scratch in word processing software. This approach is extremely inefficient and highly dependent on the personal experience and expertise of the sponsor, and is highly prone to errors, omissions or contradictions in document content due to negligence or deviation from policy understanding. Meanwhile, consistency of the same type of files compiled by different personnel and different departments in format and content is difficult to ensure, and professional images and management specifications of enterprises are damaged. (2) Static template multiplexing, namely, the enterprise pre-makes standardized Word or PDF template files. The business personnel manually searches and modifies the key information (such as project name, date, amount, etc.) in the template through copy-paste when required. This approach, while improving efficiency to some extent, is extremely inflexible. When the purchasing scene changes or the regulation system of the enterprise is updated, a great deal of manpower is required to be input to check and modify the stock templates one by one, and the maintenance cost is high. More importantly, the static templates cannot realize dynamic assembly and logic control of the content, and cannot meet the requirement of sections or clauses needing flexible adjustment in complex purchase projects. (3) Primary informatization systems some purchase management systems provide file generation functionality, but are generally simpler to implement. For example, the system may only support populating simple business data (e.g., vendor names, project numbers) in fixed document paragraphs, lacking fine management of the overall structure of the document and complex business logic. Such systems have the following drawbacks in general: The flexibility is insufficient, the template structure is stiff, and the templates are difficult to be rapidly customized and adjusted for different scenes in an intuitive mode (such as dragging). The lack of reusability, namely the inability to abstract the common reusable business terms (such as payment, acceptance criteria, default liabilities, etc.) in the procurement file into independent "building block" units, results in a template library that is bulky and redundant, and difficult to manage and reuse. The legal effectiveness guarantee is weak, the generated electronic document is difficult to integrate electronic signature (CA authentication) conveniently so as to generate a final document with legal effectiveness, and often, off-line processes such as printing, signing, scanning and the like are still needed, so that the full-process electronization cannot be realized. Therefore, how to provide a templatized purchase file generation method and system, so as to achieve the improvement of the intelligent level and the operation efficiency of purchase management, becomes a technical problem to be solved urgently. Disclosure of Invention The invention aims to solve the technical problem of providing a templatized purchasing file generation method and a templatized purchasing file generation system, so as to improve the intelligent level and the operation efficiency of purchasing management. In a first aspect, the present invention provides a templated purchase file generating method, including the steps of: Step S1, creating a corresponding purchasing file template based on a preset purchasing scene, wherein the purchasing file template adopts a layered structure and is provided with a template information layer, a template label layer and a catalog configuration layer, and the template label layer is used for abstracting service contents into reusable label components; step S2, storing each purchasing file template and label configuration and catalog configuration associated with each purchas
