Debit memo is not getting created from CRM to ECC

Hi All,

We are not getting proper partner_guid in ECC from CRM.Middle ware setting is perfect. We debug and check-in the ECC system, partner guide exists in CRM properly but when moving to ECC via Queue-it is truncated. In CRM - 32Char bt in ECC it is - 12Char.

FM in ECC - CRS_SERVICE_BILLING_PROCESS .

Any suggestion .

Thanks in Advance .
