PO rejection in SNC does not update the items in MM with ORDR

Question

Hi experts,
I have got a problem with the integration of ORDRSP Idocs in MM (ECC6 - SAP_APPL 604) in the case of a PO rejection in SNC (7-SP7).
The ORDRSP is not integrated in MM and is marked with an error message refering to a quantity difference between the Idoc and the PO.
Associated to the ORDRSP Idocs we are using the process code ORDR, and I have checked that if we use the ORDR_SUS process, the integration works well and the items are rejected in MM !
But I haven't found much informations about the differences between ORDR and ORDR_SUS.
Could anyone tells me about the side effects of using ORDR_SUS in place of ORDR ? Or if there is a way to make the PO rejection works with the ORDR process ?
Thx.
Vincent

Hello Bharath,
Yes we have the same problem on the Idoc status but didn't fix it.
Here is the SAP answer about the rejection process :
With regard to the SNC->ERP integration of the rejection, the process
code in ERP inbound processing has to be set to ORDR_SUS (-> transactionWE20). Otherwise the rejection will not set the deletion indicator in
ERP PO and as a result the approval process is not triggered when the
supplier rejects a PO item.
Kindly refer to the word attachment showing the WE20 screenshot.
The purchase order can transfer the rejection information to the
customer back-end system. The ReplenishmentOrderConfirmation XML messagecontains a corresponding AcceptanceStatusCode. However, to integrate therejection of a purchase order item with the customer back-end system
using IDocs, you must implement SAP Note 962849, so that the deletion
indicator is set on the purchase order item in SAP ERP.
Kindly implement the following note as well:
1458562 - ROC_Out not sent if the supplier rejects a PO item
With the implementation of the this note, the R/3 backend system should
get updated once the supplier 'Rejects' the item.
Kind regards,
Vincent
