Error while service order getting copied into ECC

Hi,

On saving the service order I am getting an error sayin : Error occurred while copying the document into ECC. I have checked the detailed error log on WEBUI. It is showing the below:

"Enter a (default) purchasing group for material group 900000000 (Notification E CRM_SRV_LOG_EXT_OLTP 002)"

Could you please let me know, Where do we maintain the above data.

Thanks,

Sandeep
