MM-SUS: PO not sent to SUS

Question

Dear experts,
We are on SRM 7 and ECC 6 EhP 4 and we want to configure the MM-SUS scenario.
We have done the following:
- Configured scenario SE_Service_Procurement in Integration Directory in XI system
- Activated Business Functions ESOA_OPS01, LOG_ESOA_OPS_2, LOG_MM_CI_1, LOG_MM_P2PSE_1 in ECC system
- Activated in transaction SWETYPV in ECC system
        BOR Object Type     BUS2012                            CHANGED     WS53800008       No errors
        BOR Object Type     BUS2012                            CREATED     WS53800008       No errors
        CL Class ABAP     CL_SE_PUR_PO_WF_OUT     CHANGED     WS53800008       No errors
        CL Class ABAP     CL_SE_PUR_PO_WF_OUT     CREATED     WS53800008  No errors
- Created class Z_SUS_VENDOR with charasteristic Z_SUS_VENDOR for class type 010
- Set this class for vendor
- Implemented BADI PUR_SE_PO_INTERFACE_OUT_SELECT
But we can't send PO from MM to SUS yet. Interface PurchaseOrderERPRequest_Out_V1 was not triggered.
We have got error for workflow WS53800008 (in SBWP):
"Object CL_SE_PUR_PO_WF_OUT method EXECUTE cannot be executed."
Thanks in advance for your help.

Hi Nikhil,
Thanks a lot for your reply.
Unfortunately, this notes couldn't solve my problem.
First of all I tried to send regular PO, not service PO.
And one detail more: Instead of service PurchaseOrderERPRequest_Out_V1 system triggered service PurchaseOrderERPReplenishmentOrderCollaborationNotification_Out.
Thanks in advance for any help.
