SAP ODATA Service (for creating a record)

Dear All

We have developed a ODATA service to query data as entity set or Query data based on a key value.

It is working fine.

However, We like to have a following

1. We have a Z-table  ( Say contacts ).  This contains 10 to 11 fields

We need to create a odata service that inserts records into this z table. ( I developed one Z function to insert a record )

after creating the create method,

How i can get the 11 values from the request. 

Can someone give me a hint.

Regards,

Venkat
