This particular issue that Loxley is having is related to the WCMS 3.01 release. Last Monday, there was a presentation in which Khun Suban was in the call. In the presentation, it was mentioned that the previous CXC Revision State (Software Revision) field in the WCMS claim format has been replaced by the RMA (Return Order ID) field of the CARE+ Return Service. Since Thailand is not involved in the CARE+ Return Service, please ask your GSP to leave this field blank.
