D_ApplicationSetting DP Error

We are configuring the PegaCDM application. After configuring the extension DataTrasnform. While accessing the Contact, Service Account Landing Page. I’m getting the below error.

What is the configuration change to be looked for ?

We are following the installation guide Pegasystems Documentation

Error loading D_ApplicationSettings using activity {pxObjClass=Rule-Obj-Activity, pyClassName=Common-Admin-ApplicationSetting, pyActivityName=pxCallDataTransform}

Did you saveas ClassSetting_AppName and General Settings_AppName to your application ruleset and provided proper classes?

Yes, Anoop. During application initialization, Pega created the DTs in the context and in the application ruleset in the class contextComm-Admin-ApplicationSettings.

Actually we have to create both the DTs with the naming convention - ClassSettings_AppName and GeneralSettings_AppName in our ruleset by saving as the OOTB rule. Because these rules are being referred inside D_ApplicationSettings. In our applicaion we created and have set DCR classes in ClassSettings_AppName . If it is already there for you and class in already there it should work. And I hope you have already configured CDM server through wizard.
