Create Deep Entity in SAP UI5 - oData Model

[Former Member]

Hi,

I am doing a CRUD project and want to perform a deep entity creation. I've an entity Student and another is Enrollment. A Student can have multiple Enrollments. For this, I've created Association b/w these 2 entities.

Now from SAP UI5, i want to call create operation in which while creating Student record, i also want Enrollment records to be inserted into DB.

I am trying to use the following code to create the required Data object.

oNewEntry.StudentID = "000";        // Will be generated

oNewEntry.StudentName = "Xyz";

oNewEntry.Course = "ABC";

oNewEntry.Age = parseInt(25);

oEnrollment = {};

oEnrollment.StudentID = "000";

oEnrollment.CertificateID = "SAPUI5";

oEnrollment.EnrollDate = new Date(2014,03,30,00,01,00);

oEnrollment.CreateDate = new Date(2014,03,30,00,01,00);

oEnrollment.Status = "X";

oNewEntry.Enrollment = oEnrollment;

oModel.create("/StudentSet",

  oNewEntry,

  null,

  function()

  {

   alert("Student record created successfully!");

  },

  function()

  {

   alert("Student record creation failed!");

  }

);

I am trying the above code, but it always throw the following error.

The following error text was processed in system GW1 : Specified value is not a valid value for the type of an XML document                                                                                                                                                                                           The error occurred on the application server XXXXXX. The termination type was: RABAX_STATE.

Am i doing any mistake while creating oNewEntry object ? As I am able to create entity StudentSet & EnrollmentSet  individually but not as Deep Entity in one go.

Please Help.

Hi,

Thanks for you reply.

Probably this will not solve my problem because the link is about Batch operation But in my case i want to create one entity of Student but with 1 or more entities of Enrollment (using Deep Insert).
