Just to clarify here: do you intend to create Instances of existing Cases (~="Work Items") here or new Case Types ?

Hello Soumya,

Thanks for posting your query on PSC. 

From your post, I understand that the case is not getting created while invoking through activity.

Could you provide below information?

- How is the activity configured? Are you using CreateWork feature as one of the step?

- From where the activity is invoked (that is from process flow)

- What is the Pega product version used at your end.

Regards,

Rincy

To create instances of a specific class you can use below steps in your activity

1) Call createWorkPage activity with step page of that class for which you want to create the instance(Framework class)

Parameters: InsClass is mandatory- should be same class for which instance need to be created.(set parameter values before these steps)

try with OOTB pystartcase, if any error comes then try with saving that pystartcase to your corresponding casetype class of Framework class

2) Call Add activity with step page as same above and parameter flowtype with pyStartCase as above.

Now this should create an instance of the class that you want from an activity
