Analyzing Required Configurations

Objective

After completing this lesson, you will be able to explain how to configure Purchase Order Flows in an SAP System, CIG, and in Ariba Network.

Purchase Order Flow

A Purchase Order (PO) is a commercial document and first official offer issued by a buyer to a seller, indicating material or service types, quantities, and agreed prices for products or services.

It is used to control the purchasing of products and services from external suppliers.
Acceptance of a purchase order by a seller forms a contract between the buyer and seller.
A contract does not exist until the purchase order is accepted.

Types of Purchase Orders Supported:

Standard Purchase Orders
Blanket Purchase Orders
Scheduling Agreement Release Purchase Orders
Service Purchase Orders
Subcontracting Purchase Orders
Consignment Purchase Orders
Purchase Orders with Returns

Additional Information:

Schedule lines in a Purchase Order are supported.
A Standard Purchase Order can have lines with catalog material or non-catalog material.
A Service Purchase Order, using SAP ERP 6.0 EHP 0, can only have a single-level hierarchy (one parent and child line item). However, using SAP ERP 6.0 EHP 4 & higher, you can send a Service PO with service line items in up to five levels of hierarchy (1 parent and 4 child levels).
A Blanket PO with item category "B" is supported.
Price Basis Quantity (PBQ) along with different types of Account Assignment Category is supported.
Defining 2 way or 3 way match is also supported.

Pre-requisites:

Standard NACE or Output Determination configuration should be in place.
SAP Ariba AddOn package downloaded in your SAP system.
Ensure that the parameter ORDER_ENABLED is set.
- ORDER_ENABLED – Enables you to bypass the SAP Ariba code in case it is causing issues in customer specific scenario.
SAP Cloud Connector installed & configured (for Direct Connect option).
Supported middleware should be configured (for Mediated Connect option).
CIG enabled through your AN Buyer Account & you have P User info.
SAP system information is sent to CIG.
AN Buyer and Supplier relationship should exist.

Configuration in SAP System – Global Settings

Ensure that following configurations of Global Settings section are in place:

Define Authorizations: Make sure that users working on CIG AddOn configurations have necessary authorizations / roles assigned.
Enable Integration through Middleware: This is an optional activity. Maintain a parameter if you are integrating via any of the supported middleware.
Maintain Certificates: This is a mandatory activity to establish SSL handshake / connectivity between SAP system & CIG. Upload Loadbalancer certificate of CIG in the Trust Manager.
Create RFC Destination: RFC Destination is needed for transmitting IDocs. It allows you to connect from an ABAP system to an external system. Before creating an RFC destination for CIG, ensure that you have maintained CIG’s Loadbalancer certificate in the Trust Manager & you have P User & password information handy.
Create Port Definition: A port is the communication channel through which IDocs are sent. The port describes the technical link between the sending and receiving systems. Port Definition is needed to specify the way in which the IDocs are transferred to the EDI subsystem.
Create Logical System: The value created here will be used in Interface Setup program for generating outbound parameters of Partner Profile under TCode WE20.
Configure Receiver Port: Assign ports created to a specific IDoc flow based on the solutions you are adopting.
Send SAP Information to CIG: Run this (SAP Data Sync) report to send specific set f information from SAP system to CIG. This information will be used during project creation & for applying accurate mapping set to your documents.
Maintain Parameters for Attachments Support: This is an optional activity. You can maintain certain parameters to send or receive attachments for the documents where SAP standard UI doesn’t support it by default.
Map Variants & Partitions: Applicable only for SAP Ariba Sourcing Integration & SAP Ariba Procurement Integration. Define unique values of variant & partition for your SAP Ariba realms. This is required by our various export programs to apply filters & parameters while exporting data for a specific SAP Ariba solution.
Maintain BAdIs as per your requirements to further massage the data for filters & parameters before storing it in Ariba specific tables.

Configuration in SAP System – General Settings

To navigate to general settings in SAP ERP and SAP S/4 HANA for Ariba Network Transactions

Run the transaction code SPRO – The Customizing: Execute Project screen appears.
Click SAP Reference IMG – The Display IMG screen appears.
Navigate to –
- Integration with Other SAP Components → SAP Ariba Cloud Integration Gateway → Ariba Network Integration → General Settings

Ensure that following configurations of General Settings section are in place:

Setup the Interface: This program helps you to automatically create Inbound & Outbound parameters in Partner Profile for IDocs and Logical Ports & Service Names in SOAMANAGER for Web Services / Proxies.
BAdIs for Setting Up Interface: When setting up the interface, you can optionally implement the BAdI to modify any parameters.
Create Partner Profile for House Bank: Since the Setup Interface program will always configure interface for IDocs only against the partner function of type LS (Logical System), you would need to need to manually configure outbound parameters for REMADV & PAYEXT (under partner type B) to generate Payment Remittance documents & send it to Ariba Network & also optionally send the info to bank.
Configure Document Status Update: Using the document status update functionality, you can monitor status of all transactions that:
- You send from your SAP ERP or SAP S/4 HANA system through CIG to suppliers on the Ariba Network.
- Send the document status update for transactions that you receive from suppliers on the Ariba Network.
Enable Supply Chain Collaboration (SCC): If you want to enable Supply Chain Collaboration related functionality, then you need to maintain required parameter. This is purely based on requirement. Since Enable SCC is a toggle driven feature in AN, we also have provided same flexibility in AddOn code.
Enable Vendors: In this activity, user needs to maintain the vendor & company code combination in ARBCIG_AN_Vendor table (via SPRO node) for all the SAP vendors that are registered as suppliers on Ariba Network. Thus, the documents are filtered & sent to Ariba Network only for such SAP vendors who are registered suppliers on Ariba Network.
Maintain Vendor for the Outbound Transaction: This is an additional filter for outbound transactions. Maintaining "Enable Vendors" table is prerequisite for this activity. Here user needs to select the vendors that are already added in ARBCIG_AN_Vendor table & then maintain one or more message types for each vendor in ARBCIG_OB_VENDOR table (via SPRO node). This configuration helps you to further specify or filter message types per vendor that you wish to send to Ariba Network. If this table is not maintained, CIG AddOn code will only refer to AN Vendor table & will send all the message types for the vendors available in ARBCIG_AN_VENDOR table to Ariba Network.
Enable External Format Conversion: You can configure SAP system to convert the format of data to external format before sending it to Ariba Network. This parameter helps you to remove leading zeros of the object IDs such as Purchase Order Number; Material Number; Item Number; G/L Account; Asset; WBS Element; Cost Center; Internal Order; etc.
Plant Specific Time Zone Conversion: User can configure SAP system to send delivery date with Plant time zone instead of System time zone for PO/SA/SAR transaction.

Purchase Order- Configure Implicit Enhancements

Buyer users need to configure implicit enhancements to send Purchase Order to Ariba Network.

Steps

Run the TCode SE38
The ABAP Editor: Initial screen appears.
Enter LEINMF0Q for Program & click Display
The Choose Program for LEINMF0Q popup appears.
Click Select.
Note
As standard SAP’s ORDERS IDoc is not capable of handling PO changes & deletion by default, this enhancement helps to enable the IDoc to send change & cancel / delete info to AN.
Click Enhance in the application toolbar.
Select SAPLEINM from the popup.
Click Edit → Enhancement Operations → Show Implicit Enhancement Optionsto display a line after the lesen-beleg form.
Right-click the line below FORM lesen_beleg & select:
- Enhancement Implementation.
- Create Implementation.
Click Code on the Choose Type of Enhancement popup to display Select or Create Enhancement Implementation buttons.
Click Create Enhancement Implementation button.
Enter a name & description for the enhancement & press Enter.
In the package popup, specify your Z or Y package or Local Object, press Enter & save the package to a transport request.
Enter the include: INCLUDE ARBCIG_ORDER_REQUEST_LEINMF0Q IF FOUND.
Activate the enhancement and save it.

Purchase Order - Configure Service Map Key

This functionality is actually built for SAP SRM and SAP Ariba is using that. It is available from EhP 4+ (Enhancement Pack).

Configure this setting only if your service purchase order transfer from ERP to Ariba Network fails.
This usually occurs when the business function LOG_MM_P2PSE_1 is not active on your SAP ERP system.
- To have the SRVMAPKRY generated, customer needs to turn on the Business Function (BF) – LOG_MM_P2PSE_1.
You only need to implement the SAP Note (#2372821) if the standard field SRVMAPKEY is not activated on your SAP ERP system.
The standard field SRVMAPKEY in the SAP Table ESLL stores service purchase order Item ID information.
The service map key is required to identify the line numbers for the service lines.
If the SRVMAPKEY is not available, the Item ID does not populate the line numbers for the service lines correctly and the SAP Process Integration mappings fail.

Purchase Order- Implement Customer Exit

The INCLUDE ARBCIG_ORDER_REQUEST_002 is called from the customer exit for outbound purchase orders.

Steps

Navigate to:
- Integration with Other SAP Components
- SAP Ariba Cloud Integration Gateway
- Ariba Network Integration
- Application Specific Settings.
Expand the Purchase Order section & click IMG-Activity for "Implement Customer Exit for Purchase Order."
The Project Management of SAP Enhancements screen appears.
Create a new customer exit. ZARIBAPO (for example) & click Create.
In the package popup, specify your Z or Y package or Local Object, press Enter & save the package to a transport request.
Click Enhancement Assignments;
- Enter the user exit name MM06E001 & press Enter.
Go back & click Components. Then double-click the enhancement name EXIT_SAPLEINM_002.

In the new screen that appears, double-click INCLUDE ZXM06U02.
Click Activate.
Go back & click Components & then double-click the enhancement name EXIT_SAPLEINM_011.
In the new screen that appears, double-click INCLUDE ZXM06U33.
Enter the include: INCLUDE ARBCIG_ORDER_REQUEST_011 IF FOUND.
Click Activate.
Go back & activate user exit as well.

Purchase Order- Mapping Setting for Purchase Order/SA/SAR Outbound

This configuration filters out account assignment details such as G/L Account, Profit or Cost Center etc. at the company code level, when the purchase order is sent from SAP to Ariba Network via CIG. In the case of Invoice Pro, the customer may choose to send organization data in the PO to Ariba Network.
