We all are aware that SAP ARIBA is on cloud edition and can be integrated with SAP S4 HANA or SAP ERP backend / backends via CIG (Cloud Integration Gateway on cloud middle ware based on CPI).
To achieve transactional or master data flow from one system to another flawlessly, SAP ARIBA has given standard interfaces. Also, there is document routing for interfaces coming from external suppliers. However, in practice, its observed that for some cases where in CXML message is showing some other target system and hence CIG interface went in to ERROR or Failed status.
To address such cases one can easily configure the custom routing in CIG. Integration consultant must know that there is mapping possible without changing the CXML message format to handle the project situation.
Earlier customer support use to set up this routing for customer documents.
Customer support must enable the functionality of mapping custom routing via SR.
What way we can use custom routing in CIG.
We can use this routing to send data via documents within SAP ARIBA applications to ARIBA Network or to SAP ERP. We can map both inbound and outbound paths via this custom routing within CIG.
Case1- If invoice coming from Supplier portal in to S4 HANA is coming as system id “Child”, and because of which CIG document status “InvoiceDetailRequest” use to get in to error or failed. We must need to go with the custom routing. Here we should define the X Path in configuration (Path till system id equals to Child in CXML message). We should instruct the system that where ever this document comes with “Child” as system id please in CXML replace it with Action Value as “XYZCLNT100” so as to get invoice in to ERP or S4 HANA system.
Case2- If we have multiple ERP systems connected to one SAP ARIBA buying, to receive the PO acknowledgement back from SAP ERP. “PurchaseOrderExportRequest”
Company code is filtering criteria used in X path.
Case3- When ever Quote Request is been sent from S4 HANA to SAP ARIBA and if we have single endpoint (System ID for both Ariba sourcing and Ariba Procurement is same) mapped for all processes.
IDOC generated in S4 has system name as ABCCLNT100 which then we want to be replaced as CHILD1.
