Raising exception with multiple messages in RAP ?

[BODHISATTWA__20]

Hello All

In traditional SEGW when we had to return an exception with more than one BAPI error we used to use the following piece of code .

Thanks to andre.fischer we have the code to display the BAPI errors if we go by behavior implementation procedure

.PROBLEM STATEMENT :--

But we are planning to implementing our OData using RAP_QUERY_PROVIDER

In that case we tried to use the same procedure in RAP ,

Is there anyway we can use this interface to achieve the Functionality using the Message Container ??

MY CURRENT APPROACH AS IF TODAY

Raise static expression using message class.

As mentioed in the blog

Hi, what do you mean by this? Raise static expression using message class. From the blog, I didn't see how the error handling was implemented and displayed.
