Hello everyone.

I've an assignement where i need to aggregate data from the client database.

For that, I've created dedicated Table-Types that I use to store the data.

My concern is to expose (export) those Internal Tables ( based on Table-Types) through an OData service.

While I'm trying to create the ReadEntity(Read) & ReadEntity(Query) i'm getting that error :

> ' Key property Land does not have an Input mapping in the Read operation'

My function Module Import/Export looks like :

FUNCTION ZTPM_TEMP_FM.
*"---------------------------------------------------
*"*"Local Interface:
*"  IMPORTING
*"     VALUE(FM_STARTDATE) TYPE  D OPTIONAL
*"     VALUE(FM_ENDDATE) TYPE  D OPTIONAL
*"  EXPORTING
*"     VALUE(FM_T_COUNTRYGROUPS) TYPE  ZTPM_CTRYGRP_T
*"---------------------------------------------------

And his Odata Service definition :

And there the ReadEntity(Read) method.

I dont get 2 things :

As i'm trying to expose those data, why should i provide the key(s) ? I'm trying to get the result, not to provide them ..

What should I then do, if I'm wrong, to expose the results of that function module through Odata ? (I've already read a lot, but i dont get it )

Thanks for your help !
