Receipt of Supplier Confirmation  

Use

The supplier can send either a confirmation or an order change request for the purchase order (PO).

Confirmation

A confirmation contains:

●      Confirmed delivery dates

●      Confirmed quantities

The confirmation can be sent using electronic data interchange (EDI) or SAP ICH. The confirmed dates and quantities are part of the purchase order data. When the confirmation is saved, the information is distributed to SAP CRM and SAP ICH, where confirmed schedule lines are created for the sales order line items. These schedule lines overwrite all existing confirmed schedule lines.

The supplier confirmation is optional. The confirmation control key in the vendor master controls whether a confirmation can be maintained. If confirmation is not allowed, the customer can receive neither detailed availability information, nor information about rejections from the vendor concerning, for example, reductions in quantity, cancellation of items, or delay of delivery date.

Supplier Confirmation and Acknowledgement

The supplier confirmation can only be received using IDoc from the supplier. If the confirmation leads to a change in the purchase order, SAP SPM creates confirmation entries from this.

Order Change Request

If SAP SPM receives an IDoc Order Change Request, the purchase order is updated with confirmation entries from the change request from the supplier. Besides saving the PO, SAP CRM is informed about the change request using a business transaction event (BTE). As the “owner” of the process, SAP CRM decides whether the change should be accepted.

If the change can be accepted, the sales order quantity/delivery date and the purchase order item quantity/delivery date are updated with the quantity/delivery date from the change request.

If SAP CRM rejects the change, the quantity/delivery date in the sales order and in the purchase order item are not changed and a deletion flag is set.

In both cases, whether the change is accepted or not, an ORDCHG message is sent to the supplier using message control.

Supplier Order Change Request and Acknowledgement

The IDoc message types used here are:

●      ORDRSP (Supplier confirmation, Supplier change request)

●      ORDCHG (PO acknowledgement)

●      ORDNTF(Information to SAP ICH). This is based on the standard IDoc type ORDINT01.

Supersession During PO Change/Confirmation using EDI

The supersession process involves the following steps:

       1.      Check supersession in PO confirmation

Suppliers can report supersession during a POconfirmation or a PO change request. Supplier sends these requests using EDI and it comes into the ERP system in the form of IDocs.

The system parses the segments of the IDoc and checks if supersession has taken place. If a super session has taken place then subsequent processes related to supersession takes place.

       2.      Get interchangeability master data from SAP APO and check validity of supersession

Supersession master data is maintained in the SAP APO system. When supersession is reported in PO change/confirmation, the system makes a synchronous RFC call to SAP APO to get the master data and then the system checks the validity of the supersession reported by the supplier against the master data. The schedule line date is used to check the validity of the super session. If there is multiple schedule line dates reported for a single line item, then the system compares the validity of the supersession with the lowest and highest schedule line dates for the line item. Both the schedule line dates lie within the validity of the interchangeability master data. The pre condition is that supersession should be reported in the PO confirmation/change.

       3.      Change PO

System creates sub line items and confirmation entries for the sub line item in the PO. The pre condition is that super session is valid in the PO confirmation/change

       4.      Pass information to SAP ICH

The system passes the information to SAP ICH. The information is sent to ICH using IDocs .The IDocs contain indicators to inform SAP ICH that supersession has taken place. The pre condition is that confirmation entries have been created for the sub line item in the PO

       5.      Pass data to SAP CRM

 The system passes updated PO with the new sub line item data to SAP CRM. The pre condition is that confirmation entries have been created for the sub line item in PO.

       6.      Send acknowledgement to supplier

The system sends acknowledgement to supplier using EDI.
