Issue when creating CDS artifacts.

Hello Experts

I'm still following the Open SAP tutorial for development in Hana, i was trying to create a CDS artifact but i'm getting the following error:

Failed to generate CDS artifact "p12345trial.myhanaxs.ivyrepxs::partner" to schema "XYZ" as index server config switch "view_activation_for_hcp" is set. In this mode only generation to schema "_SYS_BIC" is allowed.

I thought that the DEV Schema was supposed to be there for using it during tests, is there anything else that is missing for been able to work with it?

This is the code that i'm using:

namespace p1101189trial.xstrial1.XSProject3.data;

  @Schema: 'DEV_1VKKPRJI2LZT43BFTKBIJ510A'

context user {

  type SString : String(40);

  type LString : String(255);

  @Catalog.tableType: #COLUMN

    Entity Details{

      key PERS_NO: String(10);

      FIRSTNAME: SString;

      LASTNAME: SString;

      E_MAIL: LString;

    };

};

Thanks

Francisco
