SAP Cloud SDK : Create Custom Data Source Via SDK for multiple nodes

Hi Experts,

We have created custom business object and assign Assigned Account ID as alternative key.

We have multiple node with 0,n cardinality or see below custom bo structure.

businessobject MultipleNodes {

    [ AlternativeKey] AccountID : BusinessPartnerInternalID;

    node NodeA [0,n] {

          element ID : ID;

          element Name : LANGUAGEINDEPENDENT_Long_Name;

   }

    node NodeB [0,n] {

          element ID : ID;

          element Name : LANGUAGEINDEPENDENT_Long_Name;

   }

    node NodeC [0,n] {

          element ID : ID;

          element Name : LANGUAGEINDEPENDENT_Long_Name;

   }

    node NodeD [0,n] {

          element ID : ID;

          element Name : LANGUAGEINDEPENDENT_Long_Name;

   }

}

I have tried with right click on Custom BO and select option called "Create Data Source" but my studio are getting restart and I can not able to create data source.

Kindly suggest me.what's wrong and is it possible or not.

Regards,

Mithun
