[former_member337066]

Hello Experts,

We are working on Offline Application for Android Platform. When we are updating any existing record in offline store that time we are getting

Error:value":"[-10128] The request on an entity failed because its etag did not match the request's conditions.

We are using below code for updating the record in offline

sap.OData.applyHttpClient();

oModel.update("MobCodeSet(OrderNo='5183819')", postEntry, null,

function(){

console.log(success);

}, function(error) {

console.log(error);

}, true);

Please find the attached screenshot for error.

Can you please suggest where we are going wrong.

Regards,

Ashish

Hi, ashish.sarode1, I have same problem, do you found solution?

Hello, I solved the problem this way. According to the documentation I found in this link,

https://help.sap.com/doc/d9c75eebcfa840c8a4aa4b0e6a8136de/3.0.15/en-US/e5033aa25c67486ab06505f565bf6...

It says that we must send the same eTag to the entity to be able to update.

Then... I did a read before updating and copy etag property from metadata of old record.

this.oModel = this.getView().getModel(); 
var that = this;
that.oModel.read(vPathCero, {
     success: function (oData, response) {
		that.oModel.update(vPathCero, myEntity, {
		     success: function (oData, response) {
                         // your code on success update
                     },
		     error: function (oError) {
                       // your code on error update
                     },
//////////////////////////////////////////////////////////                 
		    "eTag": oData.__metadata.etag
//////////////////////////////////////////////////////////
               });
      },
    error: function (oError) { 
    // your code on error read
   }
 });
