Odata Create/Post Method Issue

Hello Experts ,

    Currently Issue is with SAP Netweaver Gateway Odata Services .

I am Trying to POST the Records into Database table Using Odata Create Method, For that I am Using T-Code SE80 and creating GW Data Model and Consumption Model ,generating the Model . Later on tried to Run the Odata service URL in the REST client . I am Getting the Error message as "System expected a value for the type g" . I am Using POST Method here and the Content-type = application/atom+xml and also Using x-csrf-token .

In The Request Header, Passing the Data Record to be created in XML Format as shown below.

XML Format:

<?xml version="1.0" encoding="utf-8"?>

<atom:entry xml:base="http://host:port/sap/opu/odata/sap/ZCUSTOMER_RFC/"

xmlns:atom="http://www.w3.org/2005/Atom"

xmlns:d="http://schemas.microsoft.com/ado/2007/08/dataservices"                       

xmlns:m="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata"

xmlns:sap="http://www.sap.com/Protocols/SAPData">

           <atom:content >

                   <m:properties>

                   <d:empno>0000000020</d:empno>

                   <d:city>UK</d:city>

                   <d:ename>Ram</d:ename>

                 </m:properties>

           </atom:content>

   </atom:entry>

Could anyone suggest whether the Format and Procedure I am using is correct or not ? and also the reason for the error 500 Internal server error with code CX_ST_MATCH_TYPE and Message "System expected a value for the type g".

     Appreciate your Help.

Thanks,

Uday.
