Sales order not replicated in ECC from CRM

Hi,

I am facing a production error some of the  sales order are not  replicated  from crm to ecc .

I have checked smq1,smq2,smw01,smw02,slgi but no error message is there even there is no dump regarding the same.

In crmd_order there is no error display but document flow is not enable and in status tab R/3 Transfer and R/3 status  shows( A error in Distribution) & user/system  status (Open and  contains error) .

Checking the same in smw01 queue shows confirmed (fully processed) ,checking the same in glass icon its shows ERP adapter is called,No upload into ERP.

Kindly suggest .

Regards,

Shachi
