Hello Rupesh,

This particular property is made as null-able in the GW Model ? If yes you need to send ' null ' as the input value when this property field is empty while firing the create request. Check this please.

What is the payload ? can u share it for which its giving this error ?

In the below code oEntry is the payload from app frontend.

var oEntry = {};

     oEntry.Manfacture = this.getView().byId("Manufacturer");

    oEntry.Descript = this.getView().byId("Description");

    oEntry.Maintplant = this.getView().byId("MaintenancePlant");

    oEntry.Funcloc = this.getView().byId("FunctionalLocation");

    oEntry.Equicatgry = this.getView().byId("EquipCatid");

  oEntry.ExternalNumber = this.getView().byId("Equipment");

  oEntry.Objecttype = this.getView().byId("TechObjectType");

   oEntry.Manmodel = this.getView().byId("ModelNumber");

   var url = "/sap/opu/odata/sap/Z_FIORI_CREATE_EQUIPMENT_SRV";

    var oMod = new sap.ui.model.odata.ODataModel(url,true);

   this.getView().setModel(oMod);

    OData.request({

      requestUri : "/sap/opu/odata/sap/Z_FIORI_CREATE_EQUIPMENT_SRV/Z_EquipmentCreateSet",

      method : "GET",

      headers : {

        "X-Requested-With" : "XMLHTTPRequest",

        "Content-Type" : "application/atom+xml",

        "DataServiceVersion" : "2.0",

        "X-CSRF-Token" : "Fetch"

          }

       },

    function(data,response){

        var header_xcsrf_token = response.headers['x-csrf-token'];

        var oHeaders = {

        "X-Requested-With" : "XMLHTTPRequest",

        "Content-Type" : "application/atom+xml",

          "x-csrf-token" :  header_xcsrf_token,

          "Accept" : "application/xml; charset=utf-8"

        };

        OData.request({

          requestUri : "/sap/opu/odata/sap/Z_FIORI_CREATE_EQUIPMENT_SRV/Z_EquipmentCreateSet",

          method : "POST",

          headers : oHeaders,

          data : oEntry

       },

        function(data,request)

        {

          sap.m.MessageBox.show("Equipment created" + request);

          location.reload(true);

        },

        function(err){

          sap.m.MessageBox.show("Equipment creation Failed" + err );

        });

    },

   function(err)

        {

          var  request = err.request;

          var response = err.response;

          sap.m.MessageBox.show("Error in request "+ request +" Response " + response);

        });

},
