If you've just logged in with Operator [email protected] then the first thing you need to do is to create your own application, and your own operator with access to the new app and then switch to it.

Create new app as [email protected]

Then create your own operator which has the access group pointing to your new application. Log in with that operator and you will be able to do development in the generated application rulesets.

@DominiqueP16588478  Hey you cannot create anything on the Pega platform . In the dev studio you have application menu as PEGA PLATFORM click on down arrow and you see a menu click new application . And start building your application.

you need to write an activity with the following steps

1. Open the Rule-Ruleset-Version instance using the pzinskey with obj open by handle. Select lock option and release on commit option.

2 . Do property set of the pyPassword and passwordConfirm properties with some value. (To know the exact properties open the xml of the ruleset) Lets say rules.

3. Obj save write now or obj save followed by commit.
