Free goods determination in CRM

Hi all,

Got a question about free goods in CRM.

In ECC, the free goods can be determined and there is no problem with it.

In CRM, the customising was set up in the exact same manner (spro->CRM->Basic functions->free goods), create condition type, create free goods determination procedure and assign free goods determination procedure was done correctly.

When I debug through some of the free goods function module (CRMFREEGOODS*EC) in CRM, I can see the correct free goods pricing procedure being determined, but the product GUID does not appear inside the function module.

Is there any where else that I can look to find out more to troubleshoot?

Has free goods ever worked in CRM before?

Thanks!
