Hi Carol
I'm not able to figure out why is it doing XML parsing when I'm sending in json object.
Its very misleading, but it is one message for both types of parsing.
It is probably best if you start a separate post for your problem.
If you have checked OSS and implemented the outstanding Notes re Batch processing and have implemented the necessary Methods in your MPC then it sounds like it could be a SAPUI5 issue, best to post message there.
Cheers
