Why Contract Workspace (CW) is not visible in SAP Integration Suite, managed gateway for spend management and SAP Business Network after is sent to external system from Ariba Sourcing?

If you are using Managed Gateway for Spend&Network integration with addOn, the standard integration flow for contracts created in Ariba is like below:

1. Contract is created in Ariba Sourcing and sent to External System.
2. Sourcing routes the contract to SAP Business Network.
3. SAP Business Network routes the contract to Managed Gateway for Spend&Network.
4. Managed Gateway for Spend&Network routes the document to SAP ERP.
5. Contract get's created and you can check the same in transaction ME33K.

If the contract is not reaching to Managed Gateway for Spend&Network, and it was successfuly sent by Sourcing, it is very likely that the same is failing in SAP Business Network.

Check if the Document routing in SAP Business Network for Contract Request is selected as CIG:

1. Sign in to SAP Business Network.
2. Click Administration > Configuration.
3. Click Business Application IDs and End Points (cXML and OData Setup).
4. Select the endpoint > endpoint tab > Configure Document Routing.
5. Make sure Contract Request is set to Managed Gateway for Spend&Network.

The standard flow for the ContractRequestStatusUpdate (CSUR) which is the response sent by ERP back to Ariba with the contract number created in ERP flows like below:

1. CSUR is sent by ERP to Managed Gateway for Spend&Network.
2. Managed Gateway for Spend&Network routes the same to SAP Business Network.
3. SAP Business Network routes to Ariba Sourcing.

You can refer to steps from second numbered list from the answer section, but this time make sure Contract Status Update Request is set to Sourcing in the Configure Document Routing section.

If the CSUR is not being sent out of ERP or if you are facing different issues in this scenario, refer to: Why am I not seeing PO number in audit logs page in sourcing after RFQ was awarded and PO created in SAP ERP?

Keep in mind that the CSUR document type will show up in Managed Gateway for Spend&Network not only for responses of contracts but also for Purchase Orders created from Awardings (QuoteMessageOrder), which is why the steps above also apply for contracts.
