Customer Not Created in SAP ECC

Hi,

We are using SAP C4C with integration to SAP ECC via HCI. We have set up all the data mappings and connections however when we create a new customer from SAP C4C the idoc fails with the following message "Fill all required fields SAPMF02D 0111 ADDR1_DATA-COUNTRY". All address data is populated in SAP C4C when creating the customer but is not sent to SAP ECC.

Any help would be great.

Thanks
Chris
