Use PEGA to develop a simple RPA program

Preface

Pega and RPA Maybe it's something most programmers don't know , I am working in a foreign company BPM and RPA Department work of the project , When I entered the company, I encountered the problem of scarce technology learning resources , So here I will record some knowledge accumulated from my study and work .

One 、Pega What is it?

Pega In general, there are two things you can do ——BPM(Business Process Management) and RPA(Robotic Process Automation). One of the best things about it is to develop applications without code development , The whole development process is visual . In this way , You can build scalable automation applications , And introduce many other necessary functions from the application . Of course , If you like code , It can also be in Pega Easily embed Java perhaps C# Code .

BPM（ Business process management ）

The business processes of large enterprises are very complex , And requires efficient and automated repetitive operations , For example, an enterprise ERP The system has very complicated logic , This is very complicated to implement in code , And it is difficult for later programmers to understand these processes ,Pega It is for this reason that , It can build and display the business process in a visual way , Just like drawing a flow chart , Development convenience 、 It is also easier for latecomers to understand the process , This is called BPM.

RPA（ Robot process automation ）

For example, an enterprise's electronic reconciliation system has a lot of repetitive work , The accountant needs to click constantly , Comparative data , Confirm the bill, etc , These jobs can be used RPA To complete , Tell the operating method of this work in a visual way Pega,Pega The electronic reconciliation system will be automatically opened at the set time , Perform reconciliation , And inform the relevant accounting personnel of the reconciliation results by e-mail .

Two 、 Build a simple one RPA Program

Let me make a simple example , To open the browser automatically , Get into Bing Home page , Then search the weather in Shanghai , Select a search result , Output the weather information inside .

Create a new one Pega project

open Visual Studio, Of course, the configuration is good Pega Of VS, The configuration tutorial will not be written for the time being , I haven't figured it out yet .

newly build universal web application

Specify a web site where the program will operate
Right click the new Pega project “Project6”, add to - New item , choice universal web application, No election web application Because it only supports IE browser .

Grab page elements

Double click the new... On the right universal web, The middle interface will be opened , Click... On the left web application, Property settings will appear in the lower right corner .

startPage Is the URL of the website to be opened , We use it Bing Search engine to demonstrate .

After setting, click start interrogation, The just set... Will be opened startPage website , And a small pop-up window appears .

We usually choose the mode as select elements, Drag the bull's-eye icon in the pop-up window , Put it on the page element to be captured
, Here I grab the search box .

The crawled page structure will appear , We choose input label , Click on create

VS The search box we just grabbed appears in

Follow the method just , Grab the search button on the right side of the search box

3、 ... and 、 Construction process

newly build Automation

New Pega The project should have its own Automation1, without , Just build a new one of your own , Or right click pega project , New item

Begin to build

Add a... At the beginning of the process Execute , Then click... On the left universal web application, Select... In the property bar startPage, Set the open URL , Then select... In the action bar started, Then wait for this action , Prevent computer card , The slow opening of the browser results in an error , Then select... In the method bar start Method ,setup Connect start, Check the search box of our door , In the lower left property bar, put text Property drag in , Connect to fried. The blue line in the figure represents value transmission , The yellow line represents the flow direction . In the tool box string The method is to create a variable , Assigned to the search box text attribute , Then select the search button we grabbed searchButton, Put... In the method column performClick Drag it out , Delegate clicks the search button .

Pega RPA Process construction video

The above demonstration has already demonstrated 80% The building process of , The following is complete , The last three steps should be studied by yourself , After success , It will be the same as the result demonstration below
