Confirmation not updated with Backend document number

Hi All,

We are on SAP SRM 7. The confirmation will be posted as GR in ECC, and the GR number will be updated back to the confirmation in SRM. But, for past few days, The GR is posted successfully in backend, but the SRM confirmation is not being updated by backend doc. number(GR), and also the status is I1017(Currently Being Transferred), and not I1018(Posted in the Backend).

What might have gone wrong?

Appreciate your help.

Thanks,

Prabhakaran
