Method and device for controlling limit of document

Abstract

The invention provides a method for controlling the limit of a document. The method comprises the following steps: 302, extracting intermediate data from the document according to a predefined rule; 304, acquiring a value of a comparison item in a limit control requirement according to the intermediate data; and 306, according to the comparison condition in the limit control requirement, comparing the value of the comparison item with the value of the data item in the limit control requirement to determine whether the document exceeds the preset limit or not. The invention also provides a document limit control device. According to the invention, the dynamic data of the document can be subjected to limit control without changing the document.

Description

technical field [0001] The invention relates to a document quota control method and device. Background technique [0002] Document quota control means: before the status of the document changes, check some items on the document, and only when certain requirements are met, the change will be allowed. For example, when the document is reviewed, the product discount cannot be lower than a certain value. discount. [0003] The general method of document quota control is often to control a specific field on the document, such as quantity, unit price, amount, etc. This method directly uses the fields on the document as check items or compares data items with a target value. Then draw a judgment on whether it is excessive. [0004] In the general document quota control method, it generally has the following elements: [0005] 1. Comparison operators: including greater than, less than, equal to; [0006] 2. Comparison item: located on the left side of the operator, generally an ...

AI Technical Summary

Problems solved by technology

[0020]1. The field attribute of [Document Entity] is relatively fixed. It is a collection of information describing the document, and it is not easy to expand. If the document quota check needs to use other items , there is no good solution, unless the field attributes in [Document Entity] are expanded;

[0021]2. The data on the document has not been further processed, and it is generally difficult to meet the slightly more complicated document quota inspection requirements;

[0022]3. Program designers and developers of document quota checks will often modify the algorithm due to some special logic, resulting in instability of the algorithm, and each modification must be carried out Extensive testing;

[0023]4. Business document developer, after adding the fields required for checking the document amount on the [document entity], it may be necessary to modify the logic of the document

It can be seen that adding a control to dynamic data will increase considerable complexity, and at least modify the document entity object, which will bring a certain degree of instability
