Configuring Service /IWFND/SALESORDER

Hi friends,

I am trying to configure SAP delivered service /IWFND/SALESORDER.

I am having Central Hub Deployment Scenario, and both (Hub and Backend) systems are 740- SP5 Basis Systems. Now I installed software component IW_FNDGC in the hub system so that I can get the SAP Delivered standard oData services.

Now i went to /IWFND/MAINT_SERVICE and added system alias pointing to backend system for these services.

When I see ProductCollection, I get error saying "Function module "/IWFND/EPM_PRODUCT_GET_LIST" not found." This function module will not be available in the ECC system. So IW_FNDGC is required in the Backend system as well? But as I read, IW_FNDGC is required only in Hub system.

Waiting for your inputs
