Connector Activity Class doesn't exist
I have been trying to access an external MSSQL database utilizing these instructions: https://www.pegaxchange.com/2017/02/19/access-ms-sql-server-db-from-pega-7/ . I get an error every time I try to move past the Connector Activity Class. "The specified class must exist." Am I missing a step?
I have read over the "About generating connector rules": https://community.pega.com/sites/default/files/help_v73/procomhelpmain.htm
Is there a specific naming convention for the external database? The example doesn't seem to follow the convention (Data-Admin-DB-Table). The documents specify the Data and Work classes, but I can't get it to work.

Can you confirm that you already have the class 'GT-Instance-Work' or are you expecting wizard will create that class? This wizard uses already existing class and will not create new class.

Hi William,
Here identify the base class where you would like to create your class mapping for external table in external DB.
Generally we use int class for that.
And now to use connectors in activity we choose work class because that's where our application logic should be
For you example use as below:
Base Class :- GT-Instance-Int
Connector Activity class :- GT-Instance-Work

Thank you for your reply. Unfortunately your example doesn't work for me. I get the same error: "The specified class must exist." Any help would be greatly appreciated.

I do not have the class. I did expect the wizard to create the class. The tutorial I am following doesn't mention classes and when to create them. I get an error if I go to sysadmin > class > create. What do I need to do to specify a new base class, and when should I create one?
This is my class create error

In the document you follow its guiding for Pega exercise system application and do have a specific class .
For your application you should create your own class if you need to use it. If you just want to try out, why not use the mentioned developer exercise system so all the classes is already in built.
...And related to your class create error. You are using Pega PRPC application which is consists with Locked rulesets. Without an unlocked ruleset you cannot create a class. Simply you should let the PRPC application as it is but create your own application on top of Pega.
Since you are new to Pega I think you should understand how Pega applications work and follow the Pega System Architect Essentials course . This will help you to understand the Pega Architecture and the use of it and more importantly..How to use it .
