How to create an Odata service to update value in SAP

[Former Member]

I am an android developer , it is my first time use the sap netweaver gateway to create an android application.

I use the netweaver gateway sdk to create a List/details Application.

I can get our backend server data .

Now I need to another service to update the data.But I do not know how to get it.

There are some screen shoots.

this is our sap netweaver gateway backend , I can get the data from BasicQueryCustomer by the sdk that is auto-generated.

Now I want to get the BasicDeltaCustomers data.

In the BasicQueryCustomer I can get all the data .BasicDeltaCustomers i can get the changed data .

At the end of the BasicQueryCustomer  data there is a delta token . It is used to get the BasicDeltaCustomers  data

this is the BasicDeltaCustomers

Regards

Thanks in advance

You can try your Odata service in a rest client. You have to perform GET using the create url and save the token. Then you need to do a PUT along with token got from GET. Make sure this is working from a restClient and implement it in Android.

This might help you,

You need to create Odata service manually in the NW gateway based on your requirement, that involves ABAP coding. Then you will be able to consume it in the device. When you are doing a POST from your code you need to pass the CSRF token also also with the request then only the data will be updated in SAP.
