CRM Init load failure Errors In Source System 340

Hello

This is my first question on SDN.........could anyone help me please????

When I am attempting to do an Init load to ODS 0CRM_PROH and to MD Infoprovider 0CRM_SRVGUI, using Infosource 0CRM_SERVICE_PROCESS_H the load is failing and I get the message Errors In Source System 340.

Version is BW3.5 and CRM4.0
